"Rainman" by Wet Willie

Wet Willie is a versatile band from Mobile, Alabama that got their start in southern rock. Their biggest hit was among their first--the roll-with-the-punches tune, "Keep On Smilin'" went all the way to #10 in 1974. 

The band stumbled to get back into the Top 40 for years, finally managing to do so after expanding their musical palate to incorporate pop, funk, disco, and whatever else they could squeeze in. Somehow it worked more often than not, testifying to the talent these guys had. "Street Corner Serenade" gave them their second Top 40 hit, peaking at #30 in 1978. They followed this up with "Make You Feel Love Again," which landed at #45.

The band returned with a surprise disco hit in 1979 when the terrific party tune "Weekend" reached #29 (it deserved to go much higher than that!). Lead singer Jimmy Hall struck out on a solo career after that, scoring a couple minor hits in the early 80s with "I'm Happy That Love Has Found You" (#27) and "Fool For Your Love" (#77).

"Rainman" has nothing to do with the movie that came out a decade later. The tune comes from the band's 1977 album, "Manorisms."
