Soul-jazz and Hammond B3 pioneer Jimmy McGriff made the Groove Merchant record label his home base for the better part of the 1970s, releasing the often overlooked Fly Dude in 1972. This is McGriff at his most varied. Working with Ronald Arnold on tenor saxophone, George Freeman and John Thomas on guitars, and Marion Booker Jr. on drums, McGriff tackles a Jimmy Smith tune ("Jumping the Blues"), a Memphis Slim classic ("Everyday I Have the Blues"), and a bop touchstone by sax great Charlie Parker ("Yardbird Suite").
