I just noted a little discrepancy in the Roud index for these two. Howden Fair (only entry from Yellowbelly Ballads) has #1086, Weyhill Fair (only entry from Room for Company) has #10536.

(They both have a reference to previous source in NQ, 7S, v. That's the one with Howden Fair in, but I can't find a Weyhill reference, so they may both have the Howden one as previous source).

If you're still in touch Steve, they should probably be combined.
