Foreigner "That Was Yesterday (Single & Video)"

"That Was Yesterday" was the second single taken from the album Agent Provocateur by the band Foreigner. This song was available in four versions, as a remixed single, an extended remix, an orchestral version, and the original mix. The song was written by Lou Gramm and Mick Jones, and the B-side "Two Different Worlds" is also of note for being the first solo-written Lou Gramm song to appear on a single. The single reached number 12 on the Billboard Hot 100 chart, and also reached #4 on the Billboard Mainstream Rock chart and #24 on the Adult Contemporary chart. It also reached the Top 40 in the UK (#28), the Netherlands (#19), Switzerland (#29) and Germany (#31).

The extended remix added additional lyrics in its intro, and these lyrics can be heard in the live version from the DVD All Access Tonight - 25 - Live In Concert. The video was filmed at the Birmingham Jefferson Civic Center in Birmingham, Alabama.

AllMusic critic Bret Adams later called the song "a terrific hit single," citing its "catchy chorus" and "nifty synthesizer lick."
