I Believe It's An Instrumental Song. The Guinea Pig Gets A Massage And Is Asked By The Rabbit If He Can Act. I Know Blockbuster Is Gone. But What's The Name Of The Song In The Commercial. Does Anyone Know? Please And Thanks.

Think you're looking for this:
Jackson 5 -I want you back with lyrics - YouTube (http://www.youtube.com/watch?v=h-t31Ahc5nw)
(here's the commercial for reference... )
Blockbuster "Prima Donna Ray" - YouTube (http://www.youtube.com/watch?v=s0UfhYICJuE)

Thanks! That's Exactly What I Was Looking For.

Great! :)
