Just remembered a story from a ex-PANAM colleague, ground staff at LHR.
Elton John and Stevie Wonder were on the same Pan Am flight from LHR, Stevie with a 1A boarding pass and Elton John with an aisle seat. Elton John approached one of the Gate agents before boarding and asked her:
"Miss, I requested a window seat but it seems that the plane is already full... would you mind changing my seat for Stevie´s seat number? He won´t notice anyway..."
