Rest In Peace Davy Jones, You were always my biggest music hero in my life since Nick at Nite aired your show on tv when I was 10 and my dad took me to see you in concert when I was 12 years old (10th row of course)! Our generation forgets how special & important music used to be, and because of The Monkees I learned what musicians had the capacity to do. RIP DAVY JONES ♥ - Amanda K
