Since it says 60's, I take that as being 1960-69. Any kind of music would be good, too! Occasionally, some non-rock crossed over.
For months, I've been wanting to break out my 2ch LP of Ars Nova. Admittedly, one of my least played LP's.
Joe Cocker did a great cover of "Do I Still Figure on Your Life" on Honeybus.
Some more 60's:
Indian Rope Man- Julie Driscoll, Brian Auger & the Trinity
covering Havens, a big hit in UK, barely a ripple in US
"kiss him quick, he has to part"
That Eddie Harris and New Colony Six...WOW! Great tunes!
