The shower is my time to open up my operatic chops, because of the enormous echo. You sound five times as big in the shower, so I break into some "Nessun Dorma" [from Giacomo Puccini`s "Turandot"] or Pearl Jam. You`ve got to go big when you`re in the shower. There`s no half-singing in the shower, you`re either a rock star or an opera diva.
