Goodwill and a sunny disposition go a long way, in my experience. If getting old counts as a disability, I'm now chronically reliant on others for even the most menial of tasks. Luckily, we're a family band (I drum, our eldest on guitar 1, our youngest on bass...), with a couple of long-standing family friends for guitar 2 and singing/front man. It's true we don't gig much of late (mostly due to my incapacity, but not only...). When we do 'go out', I set up my drums, which consists of me sitting on my drum throne unpacking my cymbals whilst the singer and or youngest empty the cases of their drums and set 'em up in front of me. I'm not averse to coiling up a cable or two when tearing down, but only after a reasonable hiatus as I recover enough energy to get up off the floor where I've been lying, flat on my back, trying hard to breath again. Handicapped..? Not 'alf..!
Nevertheless, and despite all this kerfuffle, we're still performing sporadically, and there's a fine spirit of camaraderie which enables us all to pull together, laugh at the tough moments and enjoy even more the highs. It certainly wouldn't be supported (nor supportable...) in any other type of formation, and is not really to be countenanced for regular gigging, even on a one-a-month basis. I'd need ambulance support and a pair of nurses bearing oxygen to be able to tour..!
