Are you in a band with, or have you been in a band with, or are you, a great singer? What famous bands have or had great singers? Is Mick Jagger a great singer? How about John Lennon or Paul McCartney? Freddie Mercury? FWIW one of the bands that I am in now has a great lead singer, and I have been in two bands in the past with great singers, but all of the rest have just been average singers. Does having a great singer in the band give you a better chance of success?
