Madera Speedway data and concert informations

1975,i was just married,i was 19, we went to this concert,smoked slot of weed,my ex had helped build the stage so he received two tickets,I met a friend of his that night by the name of Scott,little did we know we would be married ten years latter,Scott and I and it was the best 30 yrs of our lives,he passed away 5/28/16, I would sure love a list of Performer's that were there in Sept and also the bands from June or July of the same year. Thank you, Items L
