Here’s an article about two concerts, but I don’t know the name of the magazine (could it be Diario de Ibiza?) or when it was published. My guess is early 1980s because of the reference to the Paramusical Workshop, so I’ll give it a time stamp of 25 Dec 1980.
Pat played tuba thru hi school and college. Where did all this talent for so many instruments come from? He is to be envied.
