I was part of a whole shipload of WWII merchant marine/coast guard guys who washed ashore on a deserted island in the Pacific. We had a functioning radio and a baby grand piano. I don't remember what make. It wasn't a Bosendorfer because we agreed that it was better than a Bosendorfer.
We spent years on that island, just working on the piano and fixing it up and playing it. The war ended and we were well into the '50s before a ship finally appeared in the lagoon. I was thrilled about rescue, and I tried to make my way down to the lagoon by the quickest, most direct route across the island, but there wasn't really any way to do that. It was a lot like Santa Cruz's street layout that way.
Then I woke up and realized that the boat down in the lagoon was the Minnow, from Gilligan's Island.
