The song was recorded many times during sessions for The Beatles. During the 18 July 1968 sessions, the Beatles recorded a version of the song lasting 27 minutes and 11 seconds, although this version is rather slow and hypnotic, differing greatly from the volume and rawness of the album version. Another recording from the same day, originally 12 minutes long, was edited down to 4: 37 for Anthology 3. On 9 September, 18 takes of approximately five minutes each were recorded, and the last one is featured on the original LP. After the 18th take, Ringo Starr flung his drum sticks across the studio and screamed, "I got blisters on my fingers! '' Starr 's shout was included on the stereo mix of the song. At around 3: 40, the song completely fades out, gradually fades back in, fades back out partially and finally fades back in quickly with three cymbal crashes and Ringo 's scream (some sources erroneously credit the "blisters '' line to Lennon; in fact, Lennon can be heard asking "How 's that? '' before Ringo 's outburst). The mono version (originally on LP only) ends on the first fadeout without Starr 's outburst. The mono version was not initially available in the US as mono albums had already been phased out there. The mono version was later released in the American version of the Rarities album. In 2009, it was made available on the CD mono re-issue of The Beatles as part of the Beatles in Mono CD box set.
