Marshall Auditorium is a 1400-seat venue that is still in use today. It was originally built on the Marshall Jr. High Campus in Clovis. I think the site is now a middle school.1968: In honor of its 15th anniversary, a local Clovis radio station sponsored a concert at Marshall Auditorium featuring Glen Campbell with the Coachmen and the Campbellmen. Tickets, which were sold through the station as well as at the Village Record Shop, were $3.50 for general admission, $4.50 for reserved seating and $2.50 for those willing to sit up high in the balcony.
The Coachmen...
In the '60s, there were several groups by this name, but I am guessing that this is the same group that opened for the Beach Boys about the same time Glen was asked to play for them.
The Campbellmen...
This certainly sounds like something Glen put together. It's about 3 hours to Albuquerque. Just a wild guess.
