I like Steeleye Span's "Black Jack Davy" rather than Alfred Deller's "Wraggle Taggle Gypsies." Anyway, Bronson recorded 127 variants (and a few more in vol. 4)of this very familar ballad (or, group of ballads, we should say) in The Traditional Tunes of the Child Ballads. Most of them are given words separately along with the music. How varied they are!
