Very true. You sinply don't have the luxury of taking the time to sort it all out when the unexpected happens (and it will). That's why I feel much more comfortable staying away from any form of pre-arranged, pre-programmed, or pre-packaged performance. It only works well if everyone and everything stays on script. Solo or small group setting for me. I like the flexibility and comfort of not caring if a 'guest' singer wants to do a traditionally slow song fast or vise versa. Plus, it's a lot less to remember if you only play one instrument (and are old ). Just me, though.
