"Um, Um, Um, Um, Um, Um" was written by Curtis Mayfield, recorded by Major Lance and produced by Okeh label president Carl Davis. It was released as a single in December 1963 and was Major Lance's third release to make the Billboard Hot 100. "Um, Um, Um, Um, Um, Um" was his most successful hit peaking at #5 on the Hot 100 in February 1964 and reaching #1 on the Cash Box R&B chart. In 2011, the original Major Lance recording was used in a television commercial for Kraft mozzarella cheese.
Saw Gil Scott Heron live in the early 90's ..absolutely brilliant show and one of the best concerts I've been to, along with seeing Hugh Masekela live.
Dunno how many people here have heard the 'Amnesia Express Tales Of Gil Scott Heron' live lp but it's an excellent album and well worth checking.
