Being (almost) 31, I don't have Lennon memories like you guys, but like I said, it feels weird knowing I was on the Earth the same time as him. Bon Scott and John Bonham, who are two other rock stars who died in 1980 that I love, also fall into the same category. I missed Keith Moon by three months. I obviosuly remember George Harrison passing on, but the most bizzare rock star death happened on Dec. 8th (2004) for me, and that's Dimebag Darrell of Pantera being murdered......on stage! Yeah, he's not quite John Lennon, but I still grew up listening to the guy and the way he died was awful. I was supposed to be studying for finals the next day but ended up searching news sites trying to get as much info as possible.
Most underrated Beatle songs are the already mentioned "No Reply," "I Don't Want To Spoil the Party," and "Long, Long, Long." The middle song has freakish personal meaning for me and along with "No Reply" and perhaps a few other songs on BEATLES FOR SALE, show John maturing as a lyricist big time. The latter is just an incredibly gentle and beautiful George song that's hidden on the White Album. Come to think of it, "Things We Said Today," and "Not A Second Time" are quite underrated too. A lot of the early rockers like "I Call Your Name," "You Can't Do That," "When I Get Home," and especially "Long Tall Sally" don't get their due either. For Beatle songs, a lot of the early stuff is underrated because people view The Beatles as a singles band at this point and over look the better album tracks.
Can't name a worst album unless YELLOW SUBMARINE counts, but it doesn't. Worst songs? "Hold Me Tight," "Mr. Moonlight," and "All Together Now," would have to wrestle it out for that disctinction.
