Question:
Tracy Darrell Adkins (born January 13, 1962) is an American country singer and actor. In 1998, Adkins appeared on the PBS music program Austin City Limits (season 23). Adkins made his debut in 1996 with the album Dreamin' Out Loud, released on Capitol Records Nashville. Since then, Adkins has released ten more studio albums and two Greatest Hits compilations.
In March 2005, Adkins released his album entitled Songs About Me. The title track was released as its first single in December 2004. The album's second single, "Arlington", generated controversy over its content (a first-person account of a fictional soldier who was about to be buried in Arlington National Cemetery). It was followed by "Honky Tonk Badonkadonk", which became a crossover hit, bringing Adkins into the Top 40 of the Billboard Hot 100 for the first time.  2006 saw the release of Adkins' seventh studio album, Dangerous Man. "Swing", the album's lead-off single, peaked at No. 20, while the follow-up "Ladies Love Country Boys" became Adkins' second Number One single on the country charts and his first since "(This Ain't) No Thinkin' Thing" in 1997. Adkins daughter, Brianna, was featured in the "Ladies Love Country Boys" video. The album's final release, "I Wanna Feel Something", proved unsuccessful on the charts; as a result, Adkins announced that he would stop supporting the single.  In August 2007, Adkins released a single entitled "I Got My Game On". Originally, the song was planned to be the lead-off to a new album, tentatively titled Game On; however, Adkins decided not to release a full album, and instead released his second Greatest Hits compilation, American Man: Greatest Hits Volume II, for which "I Got My Game On" served as the lead-off single. The album has also produced Adkins' fastest-climbing single to date in its second single, "You're Gonna Miss This". "You're Gonna Miss This" has also become his third Number One hit on the Hot Country Songs, as well as the most successful single to date on the Billboard Hot 100 (#12), Billboard Pop 100 (#19), and Hot Digital Songs charts (#8).  Adkins released his first book, entitled A Personal Stand: Observations and Opinions from a Free-Thinking Roughneck.

Answer the question at the end by quoting:

Skyhooks were an Australian rock band formed in Melbourne in March 1973 by mainstays Greg Macainsh on bass guitar and backing vocals, and Imants "Freddie" Strauks on drums. They were soon joined by Bob "Bongo" Starkie on guitar and backing vocals, and Red Symons on guitar, vocals and keyboards; Graeme "Shirley" Strachan became lead vocalist in March 1974. Described as a glam rock band, because of flamboyant costumes and make-up, Skyhooks addressed teenage issues including buying drugs "Carlton (Lygon Street Limbo)", suburban sex "Balwyn Calling", the gay scene "Toorak Cowboy" and loss of girlfriends "Somewhere in Sydney" by namechecking Australian locales.
For Skyhooks, the replacement of Hill by Strachan was a pivotal moment, as Strachan had remarkable vocal skills, and a magnetic stage and screen presence. Alongside Macainsh's lyrics, another facet of the group was the twin-guitar sound of Starkie and Symons. Adopting elements of glam rock in their presentation, and lyrics that presented frank depictions of the social life of young Australia in the 1970s, the band shocked conservative middle Australia with their outrageous (for the time) costumes, make-up, lyrics, and on-stage activities. A 1.2 metre (4 ft) high mushroom-shaped phallus was confiscated by Adelaide police after a performance. Six of the ten tracks on their debut album, Living in the 70's, were banned by the Federation of Australian Commercial Broadcasters for their sex and drug references, "Toorak Cowboy", "Whatever Happened to the Revolution?", "You Just Like Me Cos I'm Good in Bed", "Hey What's the Matter", "Motorcycle Bitch" and "Smut". Much of the group's success derived from its distinctive repertoire, mostly penned by bass guitarist Macainsh, with an occasional additional song from Symons--who wrote "Smut" and performed its lead vocals. Although Skyhooks were not the first Australian rock band to write songs in a local setting--rather than ditties about love or songs about New York or other foreign lands--they were the first to become commercially successful doing so. Skyhooks songs addressed teenage issues including buying drugs ("Carlton (Lygon Street Limbo)"), suburban sex ("Balwyn Calling"), the gay scene ("Toorak Cowboy") and loss of girlfriends ("Somewhere in Sydney") by namechecking Australian locales. Radio personality, Billy Pinnell described the importance of their lyrics in tackling Australia's cultural cringe:  [Macainsh] broke down all the barriers [...] opening the door for Australian rock 'n' roll songwriters to write about local places and events. He legitimised Australian songwriting and it meant that Australians became themselves.  The first Skyhooks single, "Living in the 70's", was released in August, ahead of the album, and peaked at #7 on the Australian Kent Music Report Singles Charts. Living in the 70's initially charted only in Melbourne upon its release on 28 October 1974. It went on to spend 16 weeks at the top of the Australian Kent Music Report Albums Charts from February to June 1975. The album was produced by Wilson, and became the best selling Australian album, to that time, with 226,000 copies sold in Australia.  Skyhooks returned to the Sunbury Pop Festival in January 1975. They were declared the best performers by Rolling Stone Australia and The Age reviewers, and Gudinski now took over their management. The second single, "Horror Movie", reached #1 for two weeks in March. The band's success was credited by Gudinski with saving his struggling Mushroom Records and enabled it to develop into the most successful Australian label of its time.  The success of the album was also due to support by a new pop music television show Countdown on national public broadcaster ABC Television, rather than promotion by commercial radio. "Horror Movie" was the first song played on the first colour transmission of Countdown in early 1975. Despite the radio ban, the ABC's newly established 24-hour rock music station Double Jay chose the album's fifth track, the provocatively titled "You Just Like Me Cos I'm Good in Bed", as its first ever broadcast on 19 January.
