Wear your grooviest 60s outfit. It’s 1969 and veteran composer Franz Josef Haydn is making his first trip to London where he is swept up in the dizzying world of The Who, The Beatles, The Rolling Stones, Cream, and Hendrix, many of whom had grown up idealizing his early work in Esterhazy in the 1950s, much as they had Muddy Waters and John Lee Hooker in America. All of London’s hippest gather for the premier of Haydn’s London Symphony at the Hammersmith Odeon (aka Boulder Theater) but Haydn is there for the premiere of the first rock opera, "Tommy," by Who's Mahler.
