Rockers do not cry. They can play rock and later cry, or they can be sensitive troubadours who intent to make everyone mist up, or they can be Dan Hill, but if you're going to choose the profession - nay, the calling of Rocker, then remain dry. There's no crying in baseball or rock. At most you can brush away some slight moistness at your drummer's funeral.
He'll get signed. Record companies are always looking for a good belter.
