Indeed, Dick . . . sorry, I was being lazy.

The "Bulmered" A Song for every season was recorded in 1971, and a modest search of the Coppers web site linked to from Malcolm's first post doen't tell me who recorded on it . .

Coppersongs 1 (1987)
features Bob, John, Jill, Lynne & Jon, joined on one track by Ben, Lucy, Tom, with one track from the BBC archive from 1952 with Jim & John (Snr), Bob & Ron.

Coppersongs 2 (1995)
features John, Jon, Bob plus one other whom I imagine is Jill (the track listings say All so I'm going from the sleeve picture for the fourth person . .)

Coppersongs 3 (1998)
features Bob, John, Jon, Jill, Ben, Lucy, Tom, Mark, Andy, Sean; i.e three generations of the family . .
