Maybe someone already said this, but I thought I would say it
anyway...I just rented the Shrek 2 DVD and one of the special
features is "The Music of Shrek" and there's Mr. E! He talks about
having a sleepless night from jetlag on the way back from Japan, and
noticing that Shrek was having a sleepless night too in the movie, so
he was inspired to write "I Need Some Sleep".
