I've met a few musicians, mostly alternative and lots you'd never heard of.
Most noteworthy or chances being known, all of Black Veil brides, Billie Joe from green day at a after party, all of the days grace at a pret before their show, a member of the sex pistols who I didn't know that's who he was at the time and I was incredibly rude because I was tired, all of skid row let me and my dad in their bus a couple times and Liam Gallagher from oasis's son.
Other than that just footballers, all of Bristol City (UK)'s rugby team from two years ago and many sets of football' s Bristol City teams, my dad took me to see them and get shirts signed for him.
