Does anyone know what's up with the music replacement for the NES version of California Games in PAL markets?

First off, you will see that "Louie Louie" is no longer the song you'll hear when you boot the game; instead, you'll hear the menu song. Also, the Surfing song is entirely different: whereas the NTSC version uses a song sounding suspiciously similar to "Wipeout," the theme heard on this level sounds like a typical David Wise composition heard in other Rare games.
