"I Saw Red" is a power ballad by Americanglam metal band Warrant. It was released in December 1990 as the second single from Warrant's second album Cherry Pie. The song was one of Warrant's most successful singles, reaching number 10 on the Billboard Hot 100 in February 1991, number 14 on the Mainstream Rock Tracks chart[3] and number 36 on the Australian charts and spawning two music videos.
The song was inspired by a true story of betrayal. It was written after Warrant lead vocalist Jani Lane had walked in on his girlfriend in bed with his best friend, resulting in Lane's nervous breakdown and the delayed release of the band's first record Dirty Rotten Filthy Stinking Rich.[4]
