Background: Foreigner is an English-American rock band, originally formed in New York City in 1976 by veteran English musician Mick Jones ex-Spooky Tooth and fellow Briton and ex-King Crimson member Ian McDonald along with American vocalist Lou Gramm. Jones came up with the band's name as he, McDonald and Dennis Elliott were British, while Gramm, Al Greenwood and Ed Gagliardi were American. Their biggest hit single, "I Want to Know What Love Is", topped the United Kingdom and United States charts among others. They are one of the world's best-selling bands of all time with worldwide sales of more than 80 million records, including 37.5 million records in the US.
Context: Jones, the founder and only remaining original member of Foreigner, decided to take some time off before looking to form a new lineup in 2004. On July 25, 2004 in Santa Barbara, California at Fess Parker's DoubleTree Resort, Jones appeared at a benefit show for muscular dystrophy with a brand new version of Foreigner that included: Jeff Jacobs, Thom Gimbel, former Dokken bass player Jeff Pilson, future Black Country Communion drummer Jason Bonham (son of Led Zeppelin drummer John Bonham and leader of Bonham) and Bonham singer Chas West. West was front man for that show only and was eventually replaced by former Hurricane singer Kelly Hansen, who had sent the band an audition tape and was invited aboard in March 2005, making his debut with the group on March 11 at Boulder Station near Las Vegas. During their 2005 spring tour, Chas West briefly continued with the band as a special guest, playing rhythm guitar.  Their 2005 BMG album, Extended Versions, featured the new line-up playing all their classic hits live in concert in one of the most "studio like, clean sounding" live album recordings produced.  Foreigner joined Def Leppard along with Styx on tour in 2007. They also toured extensively in their own right in 2007 - the thirtieth anniversary of the release of their debut.  In late 2007, keyboardist Jeff Jacobs left Foreigner after 16 years and was replaced, first by Paul Mirkovich then by Michael Bluestein (in 2008). And in 2008, Bonham also parted ways with Foreigner. Bryan Head was then brought in to fill the drum chair. But his tenure was short and he also departed to be replaced by the returning Tichy.  The band released a greatest hits anthology on July 15, 2008, titled No End in Sight: The Very Best of Foreigner. The anthology included all of their greatest hits plus some new live recordings and a new studio track, "Too Late", which was their first new song release since the 1994 album Mr. Moonlight and the first recorded output of the new lineup. "Too Late" was released as a single on June 17, 2008.
