Here's the album - http://www.soulstrut.com/index.php/reviews/indepth/Legwork/
If you liked that you'll love what he got up to in the mid 70's (but less innocent) http://el-blog-de-ernestoide-2.blogspot.com/2011/11/discos-belly-dance-from-middle-east_16.html Look at image 45 of 52 (I admit I did spend a while looking at some of the others......)
Notes on the Belly Dancer: This album is straight-ahead 70's funk, but according to the liner notes, "Belly Up, Temple Of Birth and Shifte-Telle Mama make up a belly dance suite written for the dancer in Jeremy's group, Daina Shukys. She danced in the studio during the recording of these tunes, recreating the interaction that happens when the group performs live." Far out!
