More than a few r&b based players have dug Squire. I have read that Mark Adams of Slave was a Squire fan. Given his tone, I could easily believe it.
And Squire admits that Larry Graham's work w/ Sly & The Family Stone was a big influence on him. Listen to "I Want To Take You Higher" and then the chorus to "Roundabout" ("in and around the lake") ...they're both channelling Big Booty!
