Not a definitive statement, but this may help...!!
The whole thing started with Threadbare Consort, back in the 70's....One of the best Accap bands, ever, up there with the Watersons, Young Tradition etc....
One LP was released, and immediately withdrawn, in 78/79? at Bracknell Fest (UK)....Ha Ha!! I've got a copy !!
The band split soon after, and some members reformed, in no particular order,as, the Dead Sea Surfers, and Spring Chickens.
Like the original questioner, I've often wondered what became of them all....I know that Celia O'Neil relocated in Vancouver, But, any more info, anyone??
I feel a re-Union coming on.....
