Triangle Productions presented Creedence Clearwater Revival at the Minneapolis Auditorium on August 22, 1969.  The Litter opened.   Dave Marrs remembers:

My buddies and I went to that show to see the Litter. We really didn’t care much about CCR. CCR came out and played their set sounding exactly like their recordings, and never said a word to the crowd. They were good but lifeless. Litter was great. This was the lineup with Mark Gallagher on vocals. Their guitarist Ray Melina had just left and I don’t know who played lead. Always great to see Dan Rinaldi on rhythm!

Jay Mattsson’s ticket to this great event!

Tom Murray of the Litter noted that they were booked for a six gig tour with CCR.

After the second or third date with CCR they kicked us off the tour because the crowd was yelling for us while CCR was still playing . oooops!  We had the Emerge album out at the time.
