Actually they had 2 hits in the 90s, with part of the material being recorded in the late 60s or 70s; as part of the Beatles Anthology (mid 90s), John Lennon's songs Free as a Bird and Real Love were released
by the Beatles, with the other Fabs matching up with John's demos.
Free as a Bird debuted at #2 in the UK and made it up to #6 in US--the group's 34th Top 10 single here.
Real Love debuted at #4 in the UK and peaked at #10 in the US. The song's British chart performance was
stymied by the fact that it wasn't on the BBC's playlist--the Beeb said they were a contemporary music
station and it wasn't something teenagers wanted to hear. (Source Wikipedia)

I must admit I did my own parody lyrics:
Old...as the hills
That's what we've all become
Old as the hills
Cold, old and grey
That's what we've all become
Old as the hills
(Paul) the songs I sang before,
Like when I'm 64
Now they're coming true...
(George) Just call me Grandpa George
Old as the Hills
