It was Mary Lou Lord's cover of Speeding Motorcycle used in a Target commercial for leather jackets, etc. I never saw the commercial, but it was used extensively for a brief period - and as I understand it, the song fades in and then out at the end.
You can find Mary Lou Lord's album "Mary Lou Lord Mary Lou Lord" most places including Amazon.
