oh dear, that's kind of shocking news! best wishes and a good and most important full recovery for michael.
i'm with lotus, better to cancel gigs if the recovery is not fully done until then and be patient before in danger of risking health. i wouldn't want him to be fixed up by doctors like some professional sports guys get dealt with, painkillers, syringes and more to be made fit, to keep the show going. but i also think they are not that kind of people and can deal with the pressure of not wanting to disappoint audiences and fans.
good thought there master ray. it would always be possible to meet and sing some songs together in a pub, storm a disco and demand the dj to play nma the whole night and dance with this fire that is all that we know...
