Thanks to everyone for taking part. I was hopeful that, despite being such a small word, MOLE, having various meanings, might still provide some inspiration. I wasn't disappointed. Unless I'm mistaken, we had 40 clues from 13 setters.
Favourites included Seamus @11, Paul @31, Ginge's letter substitution @34, Dorrien @41 (although don't see a Canadian connection) and the Rogue @43. I think, without exception, everyone produced at least one worthy clue so please don't feel miffed if you haven't been mentioned.
Like Dorrien last week, I'll announce my final 3 in reverse order:
In 3rd place ChriseE with his clever (and spookily Eggheads-synchronistic) clue @16.
Once I had the pdm re the Kenneth Grahame reference, SteveA @18 with his wonderful double vegetation misdirection was the frontrunner.
I must, however, award first place to Mattrom @28 for her lovely, inspired, concise
The Velvet Underground? (4)
Your prize is XTC in their 60s band pastiche guise, The Dukes of Stratosphear, "doing" the Beatles circa 1967.

(No extra prize, but can anyone get the connection between the two clips?)
