Hi Steve,
I hope this book has the music, as there seems to be quite a number of songs that may not have been recorded. Here's a few that mihgt help.
Watercresses: Recorded as The Watercress Girl by Tommy Morrissey on the Veteran CD "Old Uncle Tom Cobleigh and all" VIC9CD
The Bedmaking: Martin Carthy on Cd Crown of Thorn
Three Jolly Sneaksmen: Martin Carthy on CD Sweet Wivelsfiels
My husband's got no courage in him: Lorna Campbell on some Ian Campbell Folk Group CD
The Wanton Seed: Bert Lloyd on CD "Bird in the Bush" Topic label
Robin Hood and the Tanner: Wallace House on Lute : Robin Hood Ballads on the Smithsonian/Folkways label 1953 FP839. May not be on CD but available on e-music.
Bright Phoebus: on CD of same name by Mike and Lal Waterson
Jolly Roving Tar: Jeff Warner on "Steady as she Goes" 1977 Smithsonian/Folkways.
I feel some of the other songs may be recorded under a different title. I think there is a recording of "Captain Ward and the Rainbow" under the title of "The Rainbow" and also "Captain Ward". I'll get back to you on that one.
                      Hope that helps.
