There's a difference between acting and public speaking/music! I've just finished reading Impro: Improvisations and the Theatre from Keith Johnstone, one of the pioneers of impro theatre, and he delves deep into how actors literally become their role or the mask they wear, close to old religious trance state. Stewart alludes to this state: on stage he isn't Stewart, he was Hopcroft Minor, literally. Playing an instrument or speaking publicly is a bit different, you're still you.
