Here's Badfinger lip-synching "Come and Get It" on Top of the Pops.
Badfinger was a great band that was often considered heir-apparent to The Beatles. (It helped that Paul McCartney himself wrote and produced this track, and that the band was originally signed to Apple Records.)
Badfinger's legacy is marred by tragedy - two of its members committed suicide - mainly over mismanagement, money, and litigation. Still, you should seek out any of the "Best Of" compilations that cover their entire run. It's all solid stuff.
That white-haired guy at the beginning and end of the clip is Sir Jimmy Savile, and he's a good example of the type of thing that could only happen in Britain.
