1. getting a lavatory chain and handle tangled up with my guitar strap & lead..

[worn as a belt.. it was 1977.. I was 18;
bog chain 'borrowed' from a pub toilet during a pre gig p!ssup]

.. and having to play the rest of the set doubled over
with my forehead against my knees
until another band mate bothered to help untangle me.

2. running strumming & leaping up on speaker cabs without fully understanding
the physics of momentum on unlocked castor wheels...

[2a. lighter fuel and matches may also have been involved
during that particular spontaneous on-stage catastrophe...???]

3. getting so sh!tfaced before going on stage
that accidents such as that were not an uncommon occurrence..

..hmmm.. at least glad i survived to grow up to a relatively safe cautious healthy sane middle age....
