I too could not believe that Alan's passing was not marked on Mudcat.
It was indeed 4th March, and his "virtual funeral service" took place on 4th April. I too only found out through Lorna (thanks L), since facebook is alien territory to me also! (At that confusing time I could only assume that there was some private good reason why his passing had not been mentioned, and that purely out of consideration and respect a thread had not been started..)
It had been a privilege to have known Alan, a splendid fellow and true gentleman and an excellent, characterful singer. RIP, friend.
