Along the lines of Metallica's collaboration with a symphony orchestra is the British Rock Symphony, a mixture of gospel choir, orchestra, and rock band. The Rock Symphony performs classic songs from some of the best bands of all time (all of whom are, incidentally, British). These include hits from The Beatles, The Rolling Stones, Led Zeppelin, Pink Floyd, and the Who. Vocalists including The Who's frontman Roger Daltrey, Paul Young, and hard rocker Alice Cooper add to the intergeneric fun.
