R&B Performances at Dillon Gym Dances in the 1960s

I treasure memories of the great R&B bands playing the dances in Dillion Gym, easily my best experiences at Princeton.

Does anybody have information on who were the performers? It was a huge musical education for me, pointing me to lifelong semi-amateur musicianship.

Does anyone know who booked those bands? And if whoever did sees this, please share anything you’d care to. Thanks!
