I was not counting the times I was under contract as a crew member; only the times I was booked and ticketed as a passenger or "Guest Entertainer".
Just for fun, here are a few photos:
This is the Caribe Lounge on the original Island Princess in 1974; that's me, far left, playing Fender Bass:
This is the Carousel Lounge on Island Princess in 1975; I'm playing piano here. Some of you may recognize the gentleman in the colorful jacket in the middle of the photo, lower left; it's Les Brown. On one cruise that season we alternated sets with his "Band of Renown". That was probably the best cruise--ever!
