Hi Jim! A friend sent this site to us and we have found it very interesting! My husband has Meniere's as well. He has about 15% left in his right ear and nothing in the left. Some residual. We play as a duo and often with others in larger bands. Irish is the main with some old classics thrown in. He has been playing and performing since he was 16 and we are now in our 50's. Still going though! He has tried many different ways of coping with this. Sometimes with aids, sometimes not.   I think mostly that once he establishes the key away from the mic, I give him the nod, and he sings from memory. Very scary. On bad days, when his head is 'under water' he just can't sing at all.   A horrid situation for a singer/songwriter.   He said he will write himself tomorrow with explanations of his problems and attempts to conquer! All the best and keep on singing!!!
