I am very much a mediocre bass player, I never have any nerves before going on, never had, even the very first time. No idea why. My best mate is a musician of truly stunning ability across several instruments but he hates playing live. He gets nerves so bad he will throw up and feels the stress is not worth it so rarely plays live. It has always struck me as such a waste that a man of such talent suffers in this way, whereas a person like myself can just go ‘F it, it will be ok’ and just get stuck in and enjoy it.
