Hi. The peice of music you are looking for is Rappers Delight by the Sugarhill gang. possibly the first well known rap record, certainly the first to get to the No 1 position in the UK. The drums and bass on this track were actually "taken" from another dance record of the 70's, Good Times by Chic...I think you can still get Rappers Delight and Good Times on compilation CD's.
