Here's how it was first described when it surfaced:
What You're Doing (stereo) (Recorded September 30, 1964)
A truly exciting never before issued item, the 11th take of this Beatles For Sale track which was temporarily marked "best" until the Beatles remade the song on October 26. It's a bit rough around the edges but features a slate, studio chat, full vocals from Paul & John, and includes a "false ending" which was not utilized in the final version.
Until next week...
