According to an article about BP on this site
http://www.slate.com/id/2165669/
they may be releasing the BP version later.
Hope this helps, I like it better than the L.A. Version.
"This effort starts with the "Say Hey" song—the catchiest ad jingle in recent memory. BP wanted to put a song front and center in the campaign because it's easier for consumers to connect radio ads with TV ads when there's a common theme. This song's precise origins are a bit murky, but it seems to have been adapted from a track by an L.A. band called Message of the Blues. The original song—its refrain is "L.A." instead of "Say Hey," though it still has the infectious whistling—could be heard on
the band's MySpace page last week, but now it's mysteriously disappeared.
A BP spokesperson says ad agency Ogilvy & Mather will be working on a "re-release of the song based on the well-received lyrics used in the television commercials." (I predict it climbs to the mid-40s on the Billboard charts. Maybe not as successful as the
John Mellencamp Chevy song, but far less irritating.)"
