No, miss_b, the song on the Rounder re-issue of 'Songs of Seduction' is just as stupidly cut to two verses. The fragment is tantalisingly brief but it seems to have been enough to relaunch the song into the Folk Revival in the 60's. Annoyingly most people sing the chorus as as ' they went arm in arm along the road' where the Cantwells definitely sang 'They went arming along the road'.
The Horkey Load song is attributed simply to 'Cantwell family' without identifying the members involved , but it most likely would have been Aubrey and maybe John.
The National Sound Archive of the British Library has several recordings of the Cantwell family by Mike Yates and also by Gwilym Davies.
The notes by Alan Lomax (or Peter Kennedy?) to the Caedmon/Topic/Rounder recording comment:- "This version is unique in that it has a refrain and a whistled coda. The seventy-three year old [in 1956] Fred Cantwell said emphatically, as he finished the recording, 'It ain't much now, but I used to be able to whistle just exactly like a nightingale when I had my teeth.'
miss_b - I'm sorry if I implied that you might have some illicit material. Still it would have been truly wonderful if you had uncovered some new tapes.
