Thers 3 cars in the lab, and the guy is shifting the gears, and he starts making a beat to a song, what song is it? I know I've heard the song before and its been bugging me for the past week every time I see the comercial, I think its cat scratch fever, and my dad thinks its smoke on the water

Is it In-A-Gadda-Da-Vida by iron butterfly? I've seen the commercial but I'm not 100% sure.

Nope. It's Smoke on the Water by Deep Purple.

Classic guitar-learning song :D

I should have known better than to comment when I couldn't recall either of the two suggestions made by the original poster! Clearly not my area of expertise! Thanks for correcting my mistake

It's fine. We all make mistakes :)

Nope. It's Smoke on the Water by Deep Purple.

Classic guitar-learning song :D

Classic Guitar Hero song! :D

True, true

I like playing with my stick too.

... it's half past four and I'm shifting gears... ===========

guess that one, and the year!
