A comment on Youtube by a certain Mark Talbot who apparently played with Mr. Zimmer:

I had the honor of playing in a band with Deano for 6 years and he blew my mind every day. After learning about his medical condition it seemed impossible to me that he could even play drums let alone shred on them. Dean is not only a great drummer, but a beautiful person and I consider myself incredibly lucky to have had him as a band mate and even luckier to have him as a friend. I love you man and as always…I’m proud of you!
