I admit it: this was one of the primary reasons I wanted to learn how to do a full body bridge.
Some kind person has put this on YouTube:
Johnny Dawes on the Quarryman Groove (E8 7a) (from
Stone Monkey, 1986)
Tragically, they've stripped off the original soundtrack and replaced it, so unless you really like Creed, I suggest muting it and possibly playing something else instead. If you wanted to be obsessively authentic, you could go for the original
Zappa. Or you can find a chunk of it with the Dawes DVD commentary
in here.
I've linked this before, but to give some idea of exactly how difficult it is, and how terrifyingly frictionless the slate is, here's James MacHaffie (who's currently one of the UK's top trad and sport climbers)
having quite a hard time on it earlier this year.
(I'm prepared to accept that we need a "mod is a pathetic dawes fangirl" tag, btw.)
