Tv Program From 1980S

my mum used to have a vhs she'd taped off the telly in the early 80s.  it was a prog which had songs from musicals in it (perhaps hosted by paul gambaccini?) the singers/songs i particulaarly remeber were barbara dickson singing so what happens now an urray head singinging one night in bangkok.  Perhaps (??) paul jones singing something from joseph too.  how can i find what it was and if it stil exists somewhere to stream or on DVD?

Hmm there was That's Entertainment 74,76 and 85. 
which was all about musicals but I think it was narrated by different stars including Fred Astaire and Gene Kelly

Maybe have a look at IMDB and see if the various people all appear in the same programmes?
