As a person who would otherwise easily say "none", Fred Penner is the only celebrity death that hit me at all. Really sad day for me, mostly because I was still somewhat young so I remembered his show but old enough to grasp the meaning his show had beyond the enjoyment for children.
Freddy Mercury
It was all about Mr. Dressup, for me.
I just remember Fred Penner as that boring guy with the guitar that always made me turn the channel after Mr. Dressup finished.That's who I meant, actually (Fred Penner is very much still alive). His real name was Ernie Coombs.
