A first set comprising of a mixture of studio albums of just the four of them.
2nd acoustic set of Paul doing a his bit of solo or Beatles material, (acoustic only)
3rd - John the same
4th - George the same
5th - Ringo where he begins "With a Little Help From My Friends" singing the first verse slower in acapella (by himself, snapping his fingers), then stopping and asking for a little help from his friends, where John, Paul and George return and help him do a couple Beatle Ringo songs, and Ringo asks for some more help from some other friends. At this point another stage is rolled out with orchestra and other backing musicians, and a few more friends, their sons & wifes, for the set containing the more complex Beatle songs and a few solo ones mixed in. A love in. Cuz that's all you need.
There would be one song where the Dad's are sitting in chairs, watching their son's, imagine the joking around John, Paul, George and Ringo can do during this. The finale is of course John, Paul, George breathtaking guitar solos with a surprising new material added to the classic Abbey Road ending.
