We'll if we're talking frontmen without guitars (free to roam) then i'd say the man that:

- Took a flying leap off his ramp on the custom built stage and broke his ankle
-Changes clothes for every song
- Has a steering wheel as the bottom of his long mic stand
- Jumped in the crowd and smacked someone as security weren't listening
- Had the spotlight on him even though Slash was next to him
- and had Queen/Freddie as his favourite
