[Peter] Tchaikovsky's "1812 Overture" was my first go-to song in terms of getting into the zone and getting ready and then I quickly gravitated to rock and roll music in the mid-'60s with the Grateful Dead, Bob Dylan, Neil Young, The Beatles, Crosby, Stills & Nash, The Rolling Stones, Carlos Santana. So many of them are still around and still going strong. I go out to see them all the time.
