It's Jackie Robinson Day!

Today is not just the federal tax deadline day, it's the 1947 day in which Jackie Robinson broke the baseball color line with his major league debut with the Brooklyn Dodgers.

Robinson stepped onto the diamond at Ebbets Field to become the first African-American major leaguer in the modern era and go on to a have a challenging but successful season in which he was named the National League Rookie Of The Year.

MLB will honor this day by having all its players wear Robinson's number 42, which was retired for all major league clubs in 2007.

And in honor of this day, I'm putting up the YouTube video of the Count Basie Orchestra singing the 1949 classic "Did You See Jackie Robinson Hit That Ball?'
