A timely question.

If one of the marks of a great songwriter is the number of their songs that others have chosen to record -- the measure of their accaim by their fellow artists -- you have to give a big nod to the recently departed Bruce "U. Utah" Phillips. I did a tally once, and he was right up there with Pete Seeger and Ewan McColl, with over 20 songs (IIRC) that I knew of (and could remember) that others have recorded.

Cheers,
