In the early 1970s, George and his then-wife Patti visited a friend for Thanksgiving, whose wife was suffering from terminal cancer. The wife, not knowing that George and Patti were vegetarians, had prepared a huge turkey dinner. Knowing that the wife had exhausted herself cooking for them, and that she probably wouldn't live to see another Thanksgiving, they thanked her profusely and ate it anyway.
During the recording of The White Album, Ringo got fed up with being the "useless" member of the Beatles and left the group. The other three convinced him to come back, and George decorated his drumkit with flowers, including a "Welcome home" note.
The last exchange George and Ringo ever had. Ringo is preparing to leave and says goodbye, explaining that his daughter is waiting for him in Boston. George, now very sick and bedridden from his cancer treatments asks, "Do you want me to go with you?"
George's son Dhani spent the second half of the concert onstage, playing guitar alongside these legends. If you watch the DVD of the performance, you can catch them hugging Dhani, ruffling his hair, sharing smiles with him, and generally being a bunch of honorary uncles. Near the end, Dhani takes a moment to lean on Clapton's shoulder.
