Is there any significance to sharing birthdays? Astrologers would say yes. If you share your birthday with someone you admire, you might be tempted to say yes in hopes something rubs off on you.
Today (November 29) there are a number of people who share a birthday. John Mayall, who is credited as a parent of the British Blues Revival, is 88 today. Among the guitarists who passed through his band, The Bluesbreakers, were Eric Clapton (hailed as “god” by fans in the 60s), Peter Green (who replaced Clapton and about whom B.B. King said “He was the only guitarist who made me sweat” and when someone asked what happened to Clapton, Mayall said “Don’t worry – we’ve got someone better”) and Mick Taylor (who went on to play with the Rolling Stones).
Felix Cavalieri (organ and vocals with The Young Rascals) is 79 today.
Joel Coen (of the filmmaking Coen Brothers) is 67. One shot in their first film, “Blood Simple”, convinced me that I was going to follow these guys. Adude in Austin might appreciate this one.

Actor Don Cheadle (“Devil in a Blue Dress”, “Hotel Rwanda”, “Ocean’s 11”, “Crash”) is 57.
The theoretical conception date for these men would have been March 8 – International Women’s Day.
Is there any significance in this? I don’t know. Time to go ride my bike.
