Another tune that was "appropriated" with no recognition is Paul McCartney's "Lady Madonna" which is a rip of Humphrey Lyttleton's 1956 "Bad Penny Blues" with the famous piano riff played by the great Johnny Parker. And the last 8 bars of Lennon's "I'll Cry Instead" is the same as the last 8 of "Thirteen Women" by Dickie Thompson.... and on it goes....
