I don't have desperately strong opinions about what should be included other than the two most widely recognised songs of Lennon's solo career.  However, it seems to me that anyone who does have such an opinion ought first to make the case for whichever song(s) they want include on the talk page in order to gain consensus (if any can be reached).  On that understanding, does it seem reasonable to trim the paragraph and leave a note in the article to direct people to the talk page?
