Thanks to one of the YouTube users, a song is identified on "All The Best Things Are Collectives" (http://www.bumpworthy.com/bumps/78) bump.
While the artist is still unknown, the title of the song is "Groovy Cocktail". Unfortunately, it's a Turner Library Track and its unavailable for downloading.
See comments on this YouTube video with the same bump: http://www.youtube.com/watch?v=X9NnIuU46CA
That info is wrong. "Groovy Cocktail" is from Chris Winland's "Foody Music" album for APM, and it's used in the "Bear with a Hockey Mask" bump located here http://www.bumpworthy.com/bumps/72 the song is not another track from that album, either. The user who posted that is a member here, maybe he just got the titles mixed up or something.
