I've lost it for now, but there is an article on the British Library archive describing Diane as Gary's assistant, from '65 or thereabouts. Clearly the reason she keeps popping up outside the Beat Girls.
And we have three DC groups now, the Katy-Dids/Beat Girls, the Lucky Stars, and Desdemonas.
Diane mentions "Here come the pops" on her bio on the site now up for sale. Strangely she says she also appeared in a BBC production of "What Katy Did" (wihich was in 1962), maybe that was the genesis of the group name.
Rather more strangely, the bio says she appeared in the Jo Cook dancers, I think there's more to this attribution than a mistake in a photo archive.
This is an article from Tatler dated 30-04-66, the article itself is really just a general critique of girls fashions, so i wont post the rest. A slightly unflattering picture perhaps, but it shows the other side to the business of dancing in clubs during the week and not all TV glamour. I think it is Flick, Lyn and Babs shown in the photo, so perhaps they did these type of gigs on a rota basis.
I'm pretty sure this is Dee Dee and Flick with Georgie Fame, taken from an article in a dutch magazine called Teenbeat. This is just an enlarged version of the picture and the main text in unreadable (and also in dutch) so i've not reproduced that. The publication date is not stated, but it would be from mid 1966 when he released Get Away i expect. This is likely to be one of the earliest colour pics of Dee Dee and Flick, the others are from the Dickie Valentine show around the same time.
This is another from the same article, i thought it might be Dee Dee on the bike but not sure.
This one is probably from an earlier edition, again not stated. Its again not reproducible in readable quality, but the images are decent, the most interesting is probably the bottom left showing the Beat Girls in white dresses with Gary and it looks like this was the still in the Ruth, Jenny, Lyn line up.
