I like almost anything played on a piano besides country/western.
The only concerts I have ever paid to go to were performed by Billy Joel. Not only do I love his music, he is a great showman! He jokes and teases, plays the piano with his backside and lays across the piano like a saucy lounge singer. He's a hoot! He's also written classical pieces.
The last two concerts I saw he performed with Sir Elton John, also excellent!
I have some of the sheet music by these two as well as some classical. I play on my grandmother's 96 year old piano, an upright grand. It would cost more to move than it is worth to sell, but I won't part with it.
One favorite piece to play or hear is the Moonlight Sonata by Beethoven. It's like valium.
I loved all of the Muppet Show. They often featured singers and songs from the 60s. There were many beautiful songs written then. "If" is lovely, I agree PA.
I came of age in the 80s and the music was mostly awful.
Well, my doctorate is purely honorary, and Harry here is only qualified to work on sailors.
