Another Girl,”the Lennon/McCartney track off 1965’s “Help!” has never been performed live, neither by the Beatles as a group nor as part of a solo performance. That is, until Tuesday, when Paul McCartney performed the song at a concert at Japan’s Budokan, a venue the Beatles played together back in 1966. “It was sensational and quite emotional remembering the first time and then experiencing this fantastic audience tonight,”McCartney said. “It was thrilling for us and we think it was probably the best show we did in Japan and it was great to be doing the Budokan 49 years later. It was crazy. We loved it.”
