Real world music tastes of the 1960's. What did adults listen to?

I am making preparations for a ‘60s dinner for a Sunday school class of people who would have been adults in the 1960’s. My responsibility is to make the background music for them. I realize that this era is celebrated for the blossoming of Rock and Roll music, but I also believe the adults may have listened to other artists of the time. As I was a child overseas, all I listened to was whatever Mom and Dad had on the radio and I don’t remember. My sense starting out may be towards light Jazz like the Vince Guaraldi and similar Mid Century Modern artists, but am having problems finding people who remember what they liked 50 years ago. Any ideas of mainline artists to look for? Thanks!
