Burl Ives did indeed sing this song, with the fol-de-rol chorus, on his 'Songs of Ireland'LP published in the UK on Brunswick LAT 8344, in 1960. Originally recorded in USA on Decca. He called it 'Paddy and the Whale'. So did A.L. LLoyd,who was the first one I ever heard sing it with the 'Caterwaulin', Tarpaulin, Harpoonin'etc chorus. He recorded it on the Topic Records LP 'Leviathan'in 1967, with Alf Edwards (concertina and ocarina), Dave Swarbrick (fiddle), Martin Carthy (mandolin), and Trevor Lucas and Martyn Wyndham Read, as chorus singers. This was re-issued in CD, Topic TSCD497, in 1998. Available from Camsco I would guess.
