Whoever originally posted the text gave no indication as to where they got it, but presumably it was learnt from a Pentangle record, with a few words imperfectly remembered. Though some of the changes are of little consequence, others miss the sense or lose a rhyme, so I may as well indicate them all (including those already mentioned):
v1, line 2: There came along
v2, 2: he gave to me
v3, 2: For it fades
3: too pale a hue
v4, 2: That's not
3: For then I'll pluck the red rose off
v5, 2: shall whine
3: [omit How]
v6, 1: If I'm spared for one year more
2: [omit if]
4: to wash
Typically for the time (1970) Pentangle didn't bother to say where they got it (though they printed the lyric), just describing it as "traditional". I haven't so far managed to locate a traditional version of The Seeds of Love that takes quite this form and melody, so I've made a midi based on the recording -with the usual caveat that it' s not a precise transcription- and will send it to Alan for the Mudcat Midi Pages; meanwhile, it may be heard via the South Riding Folk Network site:
