I had a huge crush on him back in the day. Very sad news. Rest in peace Davy and God bless.

slept with his picture under my pillow when i was in 2d grade. LOVED him! he, mickey dolenz and Peter Tork were all on Boy Meets World in the more recent past, i am guessing that was an 80s show, my kids were young at the time.
