Ard, you got the date of the McCormack recording? I'd guess that was the one that PK was familiar with. "Raglan" was written some time over the winter of '44/45 (published in'46).                                          

Finbar Wright, my favourite tenor, has recorded "Raglan" but I was quite disappointed with his interpretation. I think it was somewhat lacking in passion. My favourite version remains the one by that notorious banjo twanger, Luke Kelly.
