There's this Mastercard commercial, and I think the 2 Johns did the music for it. The ad is called "Candy Store" for World Mastercard. This is the web site to see the ad. You will need Quick time to run it. Method :banana:

It's certainly not their vocals, so I doubt it.

The lyrics and the music sound sort of Giantish, but it's not Their voices!

Isn't it just a TMBG-esque rehash of 'Pure Imagination', as sung by Gene Wilder in the original (1971?) Willy Wonka film?

Ya the volcals are not them. Since they are excellent song writers, I figure they do commercial work on the side. Every now and then, someone is using one of their songs on a commercial. I did to contact Mastercard. They wouldn't reveal who did it. Whom ever really did it, is a closely guarded secret I guess. lol. There is a cool website that does reveal songs used on a tv commercial.Song Title info
