Yup, it's 80 big ones for the iconic Bob Dylan (real name Robert Zimmerman) born on May 24, 1941.
Changed the face of music - pop, folk, etc. - and was embraced by the exploding counterculture back in the 1960's. Didn't have the greatest voice but his songwriting skills and unique, laid pack presence pushed him to the top.
Had an on again, off again relationship with Joan Baez (another heavy hitter in the same field but with a much better voice.) They were both a force to be reckoned with.
What are your thoughts on Bob Dylan?
