Show them some attention from stage. Rock their world like they are the only one in the place. Be a decent muscian...tell them how hot they are and once you have their attention, tell them what you would like to do to them when you have them alone...really... DON'T HOLD BACK !!!! Once u score...treat them like shit. Babes love bad boys.
This formula has worked for every rocker I have ever known...
Follow it and shes yours forever!!!!
