Wow!! I don't think I've seen that since it was released nearly twenty years ago. I remember at the time, 'Faith, Hope and Charity' were featured quite heavily in teeny-pop tome Smash Hits, though they were pretty mercilessly slated.
Diana Barrand is the only brunette in the group - she has short cropped hair and sings the first line of the song: 'Why is it a man's world?' (Bless!!) Dani Behr is quite easy to spot, being about a foot taller than the other two!! The other blonde, Sally Anne Marsh, featured in the CBBC series 'Tricky Business' from, I think, 1989. This centred round a magic shop, run by Una Stubbs and Marsh (playing a character, originally enough, called Sally!!) was the main character who entered a magicians competition. I think she also sang the theme tune. Although the second series was set in the same shop, I think the cast was completely different - same theme tune, as I recall, but sung by a puppet rabbit!! The third and last series was completely different again and starred (gulp!) Bernie Winters.
As I think I mentioned in another post, Diana Barrand popped up in a tabloid paper about five years ago, having a pop at former band-mate, Dani Behr. At the time, I think the article said she was working in a sandwich shop, or something along those lines.
That video's certainly a complete change from her role as Holly in 'Turn on to T.Bag'!!
