Me piano and x1 --used to be duo -- but had to have a go at it again on my own.Agree re flexibility and I get a second person for some gigs. 2nd person can be a liability eg too loud too inflexible --to patterened- too perfect ---too afraid -- too ego ish -- too different in interpretation (my excuse for doing it my way (wrong or right) . I love to be free with audience and have fun with them so 2nd person may cut in too often on the line I may be on or as often happened to me when I get a fun bit out 2nd person changes it or takes it over. Tough business this solo tough business this duet -- I think I will stay at it-----Quote "if I dont like it chances are I may need to change the way I do it . Best wishes Pierce
