Touring personnel timeline, January - December 1963

[metal flake paint]

As per Don Malcolm's request, this is my attempt to graphically represent The Beach Boys touring personnel for 1963. Please note that rest days aren't included. Perhaps the most frustrating part is the lack of information available for the month or so between late July-late August, where Brian missed many shows and Al's presence cannot be confirmed.
Thanks to Ian Rusten for reviewing this:

Alan's presence is confirmed by a poor quality photo in a local paper for at least one show - unless Brian suddenly shrank a foot or so and adopted a crew cut.

Much appreciate this chart, many thanks.  Been trying to remember the name "Mark Groseclose" for days.
