“I Heard It Through The Grapevine” (CCR)

Early on, Creedence Clearwater Revival decided they weren’t going to be like other San Francisco bands such as Jefferson Airplane and the Grateful Dead with all that extended jamming. They’d develop radio-friendly tunes. Well, this was an exception but an 11-minute remake of a Motown classic became a signature song of theirs. I gotta think Marvin Gaye approved. The instrumental part at the end sounds free-form but is actually very structured. I could listen to this on an endless loop.
