Recording for the album instead began at EMI Studio 3 in London on 6 April, with George Martin again serving as producer. The first track attempted was Lennon's "Tomorrow Never Knows", the arrangement for which changed considerably between the initial take that day and the subsequent remake. This first version of "Tomorrow Never Knows", along with several other outtakes from the album sessions, was included on the 1996 compilation "Anthology 2". Also recorded during the "Revolver" sessions were "Paperback Writer" and "Rain", which were issued as the A- and B-side of a non-album single in late May.
