My contribution was acoustic guitar. I was involved in five of the basic tracks with Badfinger, all playing acoustic guitars, including George and myself. So there were about three of them. Well, there were at least five of us. You're talking about Phil Spector, so “More is more” [laughs].

There were at least five of us on acoustic guitars, and then Pete Drake, the steel player, came over half-way through during those five tracks, and we did some of the more country ones, like "If Not for You," which Bob Dylan had written.
