I read an article the other day in which the author asserted that the first usage of a capo by the Beatles was for the track If I Needed Someone (1965). (And yes, he mentioned the Japan concert.) This is what prompted me to want to investigate a bit further. He may be correct, but there are a few questions regarding keys that I have. Perhaps a guitarist or two will be able to offer some suggestions. http://oldies.about.com/od/thebeatlessongs/a/ifineededsomeone.htm Here is the quote I found interesting: "The basic track for "If I Needed Someone" was laid down in one take during the third session for Rubber Soul, just after work was completed on the single "Day Tripper." Two days later overdubs were added, just before work began on "In My Life." Though George later described the song as being written in D, he actually plays it in A, using a capo (almost certainly the first time any Beatle had used one)." How do you suppose the Beatles, ca. 1964 (Beatles For Sale), achieved a G-flat major tonality for Mr. Moonlight without a capo? (The only other tune I know of by the Fabs in this key is Yellow Submarine -- which is obviously later. And the brass players probably were not very happy about having to play in this key. ) I think I will have to pull Everett off of the shelf for this one. I don't believe that the key used for Mr. Moonlight is the same phenomenon as what we hear in the (specifically) La Scala performances in the film A Hard Day's Night. (I think it was the HTF poster Guido who brought the 'why' of this phenomenon to my attention.) Curious.
