From 'Wrigley's Writings' by Bernard Wrigley:

'Pie Saturday' (most likely the one that Sailor Ron mentions above)
'(Bolton's) The One Place For Me'
'The Black pud Stud (from Bolton)'
- I've no doubt there are others in the Wrigley ouvre.

Incidentally, in the intoduction to 'Wrigley's Writings' there's a somewhat puzzling acknowledgment to me. This was for a poem Bernard and I wrote together called 'Albert, the Lion and the Drink', which can be found on the CD 'Albert, the Lion & The Car PArk'.
Bernard gave me a complimentary copy of the book, and I was most flattered to read the acknowledgment.
Then I found he'd inadvertently missed the poem out of the book altogether.
Still, the thought was there...

Bernard's a most obliging chap and will, I know, be more than happy to help with songs concerning Bolton
