I can loose my place even with a simple back up going on. I practice alone so I get easily distracted while playing in a group. As a backup player, I think it helps that there are others playing backup also. I think my job as a lead player it to learn how to play what I need or
want to play and be comfortable doing it, reguardless of what the backup section is playing. My main issue is that I am not comfortable taking the lead even though I have practiced it to death. I guess that
I'm more comfortable playing backup because when I make a mistake, only the person next to me can tell.
