Fox's upcoming show Glee already turned Journey's Don't Stop Believin' into a No. 1 seller on iTunes ... and producers aren't ready to stop there.

The show won't really begin until the fall TV season kicks off, but after the buzz generated by Glee's pilot in May, rumor has it that two more songs will be released during the summer to keep people talking.

Glee co-star Chris Colfer told E Online! that Salt-N-Pepa's Push It is on the list of songs for the coming season (as well as Defying Gravity from the Broadway show Wicked).

But even better: There's video footage on the Web now of the Glee cast performing Queen's Somebody To Love. Click here to watch it. Fox has requested that similar videos be taken off YouTube, so hurry before this one disappears too.

Okay, so technically it's from 1976, but '80s fans are feeling the love. (As will Queen's remaining members when this new version hits iTunes.)

Also, Entertainment Weekly says that Billy Joel has called the show's creators and offered up any of his songs for the show. "We're thinking of doing an episode of all Billy Joel," co-creator Ryan Murphy told the magazine.
