Such groundbreaking music as Ebony and Ivory, Mull of Kintyre, the Frog Chorus, Give My Regards to Broadstreet, Vegan Sausage Rolls, Imagine, give peace a chance... which is your personal favourite?
Thomas the Tank Engine really is the highlight of all their post Beatles output...
"Nothing of value", you described the Beatles' output after 1968 ... I notice you completely skipped over the group's last couple albums with that statement, which is quite an omission. Also ignored Harrison's output in initial comment and in response diatribe.
Which leaves Lennon and McCartney, post Beatles. I wouldn't claim it's groundbreaking, but I'd say there was music "of value" from both. "Imagine" is a tune many people relate to, "Beautiful Boy" is a beautiful song, Instant Karma kinda hits, and so on. McCartney was generally not going deep lyrically with his solo music, but he did write a lot of catchy tunes (his specialty ^_^). "Live and Let Die" sits in that niche, imo, as does "Band on the Run", "My Love", and even, yes, "Silly Love Songs" (I like that arrangement, with the voices weaving, and the imelodically insistant bassline). So, this is a very subjective matter, but we simply disagree on this point.
Btw, I WAS there

, I remember that stuff, and a certain lull in the 70's at times, as FM radio became more restrictive or narrow with playlists. I was more into jazz at that point anyway, listening to hours and hours of classic stuff, going all the way back, as well as more contemporary artists.
And, my nephew loved Thomas the Tank Engine, glad to see that given mention.
