Both songs were off the poorly titled 1984 LP Slide It In, which turned out to be Whitesnake's breakthrough album in the important U.S. market; the album reached #42 in the U.S. and eventually went double platinum. As we have previously mentioned on ERV, it was around this time that lead singer David Coverdale began to focus more intently on commercial success, which resulted in significant turnover among the other members of the band. This also led to an increased focus on videos.
The video for "Love Ain't No Stranger" intercuts the band playing with Coverdale watching girls on trucks at an army base. No, it doesn't make much sense to me, either. The video is quite rare though, and the song is a solid, somewhat forgotten power ballad.
Whitesnake would go on to have huge success on their eponymous next album in 1987, and Coverdale continues to use the Whitesnake name to record and perform as of this writing.
Cool trivia fact: Whitesnake's first charting single on the U.S. pop charts (the Billboard 200), "Here I Go Again '87" went to #1.
