I once met the BBMF in the LLR between Winsford and Northwich, me going south, them north. Manch contoller asked if I had them in sight (I did, Lancaster with a Hurricane on his right wing, Spitfire on left wing), "And BBMF", he said "do you have Sierra Lima in sight?". "Yes, we have the Chippy" came the muffled voice from the Lancaster.
As we got close, the Spitfire pulled up into a lovely barrell roll, before re-positioning on the Lanc's wing tip. One old RAF taildragger saluting another - sure made my day!
