mars bar commercial from the 90's

[shogun]

I dont remember the commercial, I just remember the song. It has also been in MANY movies. It's just hard to google, because it has little if any lyrics.

its goes,

"mmm bum bum..... , mmmm bum bum, OHH YAAAAA, mmm bum bum, POP... CHICKA-CHI-POP, ...mmmbum bum"

lol, well any help will be appreciated.
