Some context: Sandman (Wesley Dodds) is a fictional character, a superhero who appears in American comic books published by DC Comics. The first of several DC characters to bear the name Sandman, he was created by writer Gardner Fox and artist Bert Christman. Attired in a green business suit, fedora, and gas mask, the Sandman used a gun emitting a sleeping gas to sedate criminals. He was originally one of the mystery men to appear in comic books and other types of adventure fiction in the 1930s but later was outfitted with a unitard/cowl costume and developed into a proper superhero, acquiring sidekick Sandy, and founding the Justice Society of America.
Dodds is one of a number of Justice Society members who finds themselves in the "Ragnarok Dimension" during the early Modern Age of comic books. The Last Days of the Justice Society of America Special (1986) wrote the post-Crisis tale of a time-warped wave of destruction ready to engulf the world. Dodds and his JSA teammates enter into a limbo to engage in an eternal battle that would allow the universe to continue its existence. This was later revealed to be a simulation created by Odin, which he intended to give to Dream as a bribe. Dodds, Dream's protege, and Hawkman, the grandfather of Dream's appointed successor are the only JSA members we see at this time. This lasted only until 1992 when DC published Armageddon: Inferno. This mini-series ended with the JSA members leaving limbo and entering the 'real' world. Justice Society of America (1992-1993) showed how the JSA members handled returning to normal life. For the Sandman, the series depicted him as an old, thin man with a balding scalp and a sharp wit. Starting with issue #1 his physical condition became important as writer Len Strazewski had him suffer a stroke at the first sign of a villainous attack. Both his age and his physical limitations became a theme writers would use in this character's post-Crisis stories.  During Zero Hour, Dodds is returned to his proper age by the Extant. Later, Wesley Dodds is shown as retired and living with Dian Belmont though occasionally coming out of it, most notably in a team-up with Jack Knight, the son of Dodds' JSA teammate Starman. When Dian is diagnosed with a terminal disease, the two travel the world together until her death.  Towards the end of his life, Dodds' prophetic dreams alert him to the identity and location of the new Doctor Fate, prompting him to contact the Gray Man, a being created from the residue of others' dreams, as well as his old friend Speed Saunders to instruct them to warn his former teammates about what he has discovered. Waiting on a clifftop, he is subsequently confronted by the powerful villain Mordru, who intends to force Dodds to tell him the identity of the new Doctor Fate, only for Dodds to distract Mordru with his gas-gun long enough to commit suicide by jumping off the cliff rather than allow Mordru to torture him into submission. His last thoughts were that his final slumber would be free of nightmares as he is reunited with Dian. His youthful but now grown-up sidekick, Sandy the Golden Boy, becomes known simply as Sand and takes his mentor's place as a member of the Justice Society of America as well as his prophetic dreams. Eventually, he takes the name of Sandman.

Some context: The Beat (known in the United States and Canada as The English Beat and in Australia as The British Beat) are a band founded in Birmingham, England, in 1978. Their music fuses ska, pop, soul, reggae and punk rock. The Beat, consisting of Dave Wakeling (vocals, guitar), Ranking Roger (vocals), Andy Cox (guitar), David Steele (bass), Everett Morton (drums), and Saxa a.k.a. Lionel Augustus Martin (saxophone), released three studio albums in the early 1980s:
After the break-up of The Beat in 1983, Dave Wakeling and Ranking Roger went on to form General Public and had a couple of hit singles in the US and Canada, while Andy Cox and David Steele formed Fine Young Cannibals with vocalist Roland Gift from the ska band Akrylykz. Drummer Everett Morton and Saxa formed The International Beat along with the Birmingham-based singer, Tony Beet, and the band released an album titled The Hitting Line on Blue Beat Records in 1990 (BBSLP 009). The album was produced by Ranking Roger and he often guested with the band at some of their shows. The International Beat toured the UK and United States before calling it a day in 1992. Ranking Roger also briefly joined Mick Jones' post-Clash band Big Audio Dynamite and performed at several live shows with the band. However, the band broke up shortly after he joined when its last album was shelved by the record company. Meanwhile, "March of the Swivelheads", an instrumental version of the Beat's song "Rotating Heads", was used in the climactic chase scene of 1986's Ferris Bueller's Day Off; the band was listed in the end credits as "The (English) Beat". "Save It for Later" was featured on the soundtrack album to 1996's Kingpin and 2010's Hot Tub Time Machine.  Roger released his solo debut, a reggae-oriented album entitled Radical Departure, in 1988. In the early 1990s, Roger joined members of The Specials to form Special Beat, which toured and released two live albums. They supported the Campaign for Nuclear Disarmament. In 2001, Roger released another solo album, Inside My Head, which included traditional reggae and ska with influences of electronica, jungle and dub. Ranking Roger's son, Ranking Junior, has followed in his father's footsteps. In 2005, he appeared on The Ordinary Boys' single "Boys Will Be Boys" and is a current member of The Beat in the UK.  Pete Townshend performed the song "Save It for Later" numerous times between 1985 and 1998. The Who performed the song twice on their 1989 Reunion Tour.  The Wonder Stuff also played "Save It for Later" featuring Ranking Roger on their "From the Midlands with Love" series in June 2012  Pearl Jam also began playing "Save It for Later" in 1996 blending it into the end of "Better Man", and it has remained in the set list for their 2014 tour.
