Although the band "performed" with an orchestra on Days of Future Passed (in actual fact the rock and orchestral segments were recorded separately), they relkied on the Mellotron when on the road to promote their work. The first time they toured using an orchestra was after 1992's A Night at Red Rocks (with the Colorado Symphony Orchestra conducted by Larry Baird). They tended to use local orchestras to the venue (but still using Baird to conduct) to reduce transport costs, although in the last couple of years of their lorchestral tours, they used a hybrid orchestra that was called The World Festival Orchestra.
The London Festival Orchestra on their album Days of Future Passed released in 1967.
