If you were going to be the only crock in the band then that's easily enough worked around (with a bit of goodwill). The problem that most of us have on Basschat is that we are - in the main - of the (ahem) more mature persuasion which means that we tend to be either crocked ourselves or in bands that contain other crocks, and even if we aren't then we just need to add "yet" to that sentence.
Many years ago, when it was still topical to describe a pub called The Duchess Of Cambridge as The Topless Kate, my back went big time just before a gig. @MacDaddy will remember that one; and he still had hair in those days. The only thing that made it possible for me to play was that @Silvia Bluejay stepped in and acted as my personal roadie, moving literally every single piece of kit that I would normally have carried - including the PA. 😱
I played almost the entire gig sitting/perched on a Kinsmann guitar stool which is why the only video I kept of that evening was this one, where I stood up. Which is just as well, because I had to do the fastest & slickest input change in history when my wireless failed halfway through the song. Note that the bass is a Mike Lull P5, which I bought after @chris_b introduced me to the wonderful world of lightweight basses.
