Brian, both can be found elsewhere (in "Bryan O'Lynn") though only the first example antedates Eliza Pace.

Thanks, but I already knew about that Brian O'Lynn 'bed' verse. What I am asking about is a 'bed' verse that conforms to the 'After the dinner' formula, and had that interesting and archaic-sounding line about spreading straw (apologies for mis-transcribing this stanza previously:

After the dinner they must have a bed
The sheets they were spread and the straw it was spread
The sheets they were short, the sides were thin
Stick close to my back, says Tom Boleyn

Eliza Pace's text sticks pretty closely to the Coverley broadside apart from those two stanzas, with little hint of oral processing. All of this suggests to me that there was another, longer version knocking around at some point, that included elements of both 'Tom' and 'Brian'.
