And of course, I absolutely loved making Lost in Space as a kid.
I had my guitar at the set of 'Lost in Space' every day. I was the only one in the cast who had a stereo in his dressing room. So while I was in school or when I was in there working with Dr. Smith and the robot, half the rest of the cast was in my trailer listening to their records that they would bring.
I did three of the original 'Twilight Zone' episodes, yes. Also, I did a little thing in the feature film, and then I wrote one of the episodes in 'The Twilight Zone's last round where I starred with Cloris Leachman and my daughter Liliana in a true sequel to 'It's a Good Life.' So, yes, I have a good 'Twilight Zone' alumni jacket.
I walk my dogs. I garden a little. I play a bit of tennis. Basically when I have spare time I'm making music.
I started playing the guitar when we started filming the pilot to 'Lost in Space,' which was way back in December of 1964, and there's a little bit in the pilot that was used in the first season where Will Robinson is sitting around some bad foam rubber rock playing and singing 'Greensleeves.'
