Fat Larrys Band - Act Like You Know (1982)

Fat Larry's Band was an American R&B/funk band from Philadelphia, Pennsylvania, who enjoyed some commercial success in the early 1980s.
Formed by drummer and vocalist "Fat" Larry James (August 2, 1949 - December 5, 1987) in 1977, band members included trumpeter/flutist Art Capehart, saxophonist Doug Jones, trombonist/alto saxophonist Jimmy Lee, guitarist Ted Cohen, percussionist and lead singer Darryl Grant, bassist Larry La Bes, and keyboardist Erskine Williams. The band's biggest hits were "Act Like You Know" (1982) (which later appeared on the soundtrack for Grand Theft Auto: Vice City) and "Zoom", which reached number two in the UK Singles Chart in October 1982. They had three other hits in the UK: "Center City", "Boogie Town" and "Looking for Love Tonight".

James also played with The Delfonics and Blue Magic, and managed the group Slick.
James died from a heart attack, at the age of 38, on December 5, 1987, and the band folded.
The opening drum break from "Down on the Avenue", from the band's first album, Feel It (Stax 1977), has been sampled by many hip hop artists, including N.W.A (Straight Outta Compton), Ice-T, Jungle Brothers and Run-D.M.C.
I also sampled 'Act Like you Know' for my Downstream Mix of Deep Forest's 'Sweet Lullaby' , which came out on Epic Records in the US. (it was on the commercially avaliable vinyl 12" and CD single, and the promotional 2X 12' vinyl.
