Grand Funk Railroad didn't play Woodstock.
While other ascendant American bands such Creedence Clearwater Revival, Sly and the Family Stone and Jefferson Airplane played Yasgur's farm this week in 1969, Grand Funk was missing.
Lead singer Mark Farner chalks it up to a scheduling conflict. They played the previous weekend at a trendy L.A. club and were locked into another gig the weekend Woodstock was staged.
It seems odd, as the band appeared at the big Atlanta festival in early July and did the Texas International Festival, just outside of Dallas, two weeks later.
Mark Farner says Grand Funk were not available to play Woodstock the weekend of August 16th through the 18th, 1969:
"It was the same... during the same time. It wasn't in our schedule, 'cause we had already had our tour schedule planned to go and do this thing and when they called for us to come to Woodstock, we couldn't make it, man. We were already booked up."
Here's a clip of Grand Funk playing in Texas in August, 1969.
