I recently listened to a 3-CD set of Chuck Berry and discovered that the first line of the Beatles' "You've Got to Hide Your Love Away" has a strong resemblance to the first line of Berry's "Confessin' the Blues" (written by McShann and Brown). Excepting one, all of the words in the first half of the line "Here I stand, head in hand, turn my face to the wall" also appear in the line "Baby, here I stand before you with my heart in my hand."
I've written before about how one of the lines in "You've Got to Hide Your Love Away" seems to demonstrate Bob Dylan's influence, but the similarity between these two lines and the fact that both are the first line seem to indicate Berry's influence, which is obvious elsewhere in the Beatles' catalogue.
