"Luanne" was the fifth and final single taken from the album 4 by the band Foreigner, and the second to feature a B-side that was not available on one of their albums, a controversial live version of their hit, "Hot Blooded". The song was written by Lou Gramm & Mick Jones and reached number 75 in the U.S. charts (meager, considering the band's other successful singles) where the album, 4 had already gone to number 1, eventually selling more than six-times platinum, but was a live staple for years to come. The live version of "Hot Blooded" was later placed on the international release of their retrospective, Records, but in subsequent re-releases has been dropped in favour of the original album version due to a couple of choice words spoken in ad lib during the song's performance by its singer, Lou Gramm.
