Joni Mitchell is sixty-seven today. I'll bet she still sounds great. Her Blue is one of my all-time favorite albums.
Also turning sixty-seven today is the literary critic Stephen Greenblatt. Greenblatt is probably the foremost Shakespeare scholar today, and his biography Will in the World, which tries to understand Shakespeare through his historical context, and particularly the realities of everyday life in Elizabethan England, is a great piece of writing; I remember not being able to put it down.
