OK, for years, I have sporadically been in positions where I've had to do backup vocals while playing. My voice is OK for backing, but unless the vocal lines match the structure of what I'm playing, I have a massive amount of trouble making it happen. It would really help our sound to have the additional backing vocals and we're not super-keen on bringing in a dedicated backing vocalist. Anyone have any tips, tricks or techniques to help with singing and playing at the same time? Is it just a case of practice, practice, practice or is it something you have or you don't have? Damn you, Sting, Paul and Geddy (amongst others)!
