50 Years ago today, The Beatles entered Abbey Road Studios to begin work on what would become their 9th, studio album. The first song they tracked was "Revolution 1". It began mainly as an acoustic tune. The sessions went well into the night with about 18 takes of the slow, bluesy jam recorded. One of them said to have lasted over 10-minutes. John was recording his vocals while lying on the floor and getting testy. (Overdubs would bring the total number of takes to 20) The sessions proved to be four individuals (with four different opinions at times) instead of a Band vibe. John would end up arguing over which version of "Revolution" would be released. Some say this was the first Beatles song to make a political statement, and maybe that's why Paul resisted it being released. In the end, the rest of the band thought this was too slow and they cut another version in July of '68 at a faster pace with more electric guitar.
