The mention above of 'The Grey Cock' reminds me how much I love the very non-trad version of it that Eliza Carthy sang with Salsa Celtica. They renamed it 'Grey Gallito', sang the refrain words in Spanish & put it all to a Cuban rhythm. I dare say that taking all these liberties would not find favour with some of you, but it's an amazing track and has(IMO) Eliza's best-ever recorded vocal.

And I enjoy it as an alternative 'take' on the tradition, not a replacement of it.
