I have seen The Beatles in concert twice. The first time I saw them was not intentional as I had gone to a concert at a theater in London to see Roy Orbison and Chuck Berry. Looking back the supporting line up was amazing. The first half had Gerry and the Pacemakers (another Liverpool group) The Animals (from Manchester) and the great Chuck Berry himself closed the first half. The second half opened with The Rolling Stones and they were followed by The Beatles and then Roy Orbison closed the second half. What a show!
