I hope this isn’t too long. I was misinformed that Gale Storm who also died recently (06/27/09) was a member of the Love Boat Cast and Crew. But in the process of googling her noticed that 520 people have guest starred on "The Love Boat".
Here a list of those cruise ship passengers.
Sorry late comers list has been deleted, there were 520 stars/guest stars and hence 520 lines, but here's the link.
