Oh, yah...

It's Esther's birthday.

The only reason I know this is because Tracks used to throw Madonna birthday parties, and the question for the prize every year was 'which famous icon died on Madonna's birthday?'.

It was Elvis.

My friend Sarah is a huge Elvis freak, and she knew the answer [actually it's funny that they used it every year, but no one remembered].

Fans gather for Elvis death anniversary
