Here are two more photos from the University of Waterloo 1965 concert. The quintet personnel (l to r): Doug Wicken (bass); Joe Lucchetta (guitar); Jack Kaplun (drums); Paul Cross (alto sax); Clarence Brodhagen (trumpet).
The trio photo (below) shows Wicken, Kaplun, and Bill Metcalf (piano).
I believe that the photos were taken by Don Cooper, who lived in Guelph, ON.
