"I think the drummer, lower right, in the photo is Harvey Wanless. I know that Harvey played with Peter Marks for a time including,I believe, some road work into the US. Harvey, Ted Keehn and I played backup for Peter Marks occasionally at the Tillicum Club and some other similar venues. As I recall, Peter Marks had spent some years on touring in the US before moving to Victoria. I have no idea of the identities of the bass and guitar players in the photo." Jon McGrath
For physical events that happen at a specific time. For example a concert, or dance performance. If there are multiple shows, you can still duplicate your event to cover them all.
