Beatles song titles that appear in other Beatle songs

Here are 20 Beatle song titles which appear as lyrics in other Beatle songs. For example the title "Honey Pie" appears in the lyrics of the song "Wild Honey Pie". I've left some very obvious ones out (such as Revolution and Honey Pie) and I've also not included some single word titles like "Help" and "Girl" which appear in a number of other songs. This is my first quiz on Jetpunk so please be merciful with your comments. I may have missed some and there may be some valid answers which I didn't think of. All feedback welcome and any errors will be corrected ASAP. Thanks!
