Here's clip 1 of 6 on the Texas Pop Music Festival in Dallas, 1969. 

The sky is shown in a park on a sunny day with the shade of trees blocking the sun. The flame of a kerosene or oil lamp is shown. The lamp is between two men asleep camping outside in a park by a lake or ocean. It’s dusk or sunrise. A classical flute version of the Battle Hymn of the Republic plays.

Cars and a van are shown at a campground by the ocean or lake at sunrise. People are asleep camping outside as the sun comes up. A straw hat sits on the antenna of a Volkswagen Bug and waves in the wind as sun rises over the ocean. People are asleep on the sand. The side door of a VW Bus is open. Some people walk and smoke along the shore. Classical flute version of the Battle Hymn of the Republic plays.

People camp on the sand on a beach next to their cars and trees. Some people wade into lake or ocean with a box. Sun is setting or rising and glittering off water.

People are sleeping together outside on grass or sand with an acoustic guitar at sunrise. One couple has a baby. The baby wakes up the mother.
