As someone in his mid 20's with not much background in music from the 60's, 70's and 80's I can still say this was an excellent show. He does some great pieces from each era and plays and sings very well. I loved the fact that the music was not being super amplified - louder never means better when it comes to quality audio.
If you appreciate music, you should check out this show regardless of your age though the crowd will most likely be 40-50+.
Other than a few set pieces he uses to transition from each era (60's to 70's to 80's) he takes requests from the audience so each performance will be different.
It is a very relaxed setting. Tables provided for larger groups and couches for the VIP tickets. Otherwise you will get to sit in a row of chairs.
Well worth the ~$15 price of admission. Show ran about 1 hour and 15 minutes.
