Fans have been lobbying for a B-sides compilation for years, but unfortunately S&TB have no control over that. Apparently Polydor, the label most of their albums and singles were released under, refuses to allow the license to anyone to release a b-sides compilation. Last I heard, the fan club was still asking people to email Polydor (or whatever record conglomerate they're under now) once a week to request a b-sides compilation. I don't think it's gonna happen, though.
I lost my gag reflex and all you got was this lousy message board posting.
