Dancing on My Own

John is painfully aware of how shy and insecure he is. Which is why he doesn't dance or play bass often. It takes a lot of liquid courage for him to go out on the dance floor, usually because he doesn't have a dance partner. But when he's in the comfort of his bedroom or properly drunk, he'll let the music takeover his body. Playing bass alone isn't the same thing as rocking out with a proper band. So he writes songs and bass riffs that way when he joins a band he'll be prepared to wow them. If he ever stops being shy long enough to audition for a band.
