Big Bang Theory is the fifteenth studio album and the first covers album by the band Styx, released in 2005. It consists of cover versions of classic rock songs. Origin In 2004, Styx performed a cover of the Beatles song "I Am the Walrus" at Eric Clapton's Crossroads Festival, where the song was received so well that it was released as a single, reaching the Top 10 in the Mediabase Classic Rock charts. The video featured original bassist Chuck Panozzo as the "eggman". The single's success resulted in the band recording this album of cover songs. The album reached No. 46 on the Billboard Top 200 Albums chart, Styx's first time in the top 50 since 1983's Kilroy Was Here.
