My Ewan MacColl recommendation is once a day... after the kids are in bed and before you turn in yourself... perhaps with a short glass of something alcoholic.

Seriously, he was so prolific, it's tough to say. If you still have a turntable, some classic recordings are 'The Best of Ewan MacColl' on Prestige International or any of his sea music recordings with A.L. Lloyd (as noted above, 'Blow, Boys, Blow' is on a Tradition CD.

All the best, Dan Milner
