When you've been playing music for as long as Neil Young has...I'd imagine things tend to get a bit monotonous.  Especially since you are required to play a handful of the same songs every night or people will leave the show feeling ripped off.

If Aerosmith don't play Dream On, or GNR skips Paradise City, or Metallica bypasses Enter Sandman...you'd just be a bit confused.

So, what do you do?  You reach back into the archives and pull out songs you've probably forgotten.  You probably get online to see how to play the damn thing.

Neil Young pulled out 2 old songs he hasn't played in 40 years.  Pretty cool.
