Apparently Bob Roberts recorded "Race of Long Ago" on "Breeze for a Bargeman" issued by Solent Records in 1981 - referenced in Musical Traditions (here):
I don't know this recording (or Webber/Fentimann's) but I do have and very much like Roy Harris' a cappella version entitled "When We Raced the Robin Adair" on his LP "Utter Simplicity" (Fellside FE044 - 1985). Roy's notes about it on the album cover say (in part) he first heard it from Jim Jewell of the Isle of Wight and "I loved it straight away – especially the line "Up from the south with a bone in her mouth"."
Yes, the "bone in her mouth" line is good. I've seen this phrase used about ships before - guess it just means speeding along?
