Yes I did ;)

seeing as he played piano on a few GnR tracks, then yes, I knew.

He also plays one of the DJs in GTA San Andreas:

Tommy "The Nightmare" Smith is a musician and disc jockey who hosts the San Fierro based classic rock radio station K-DST.

"There are two kinds of people in the world: Those who like me, and those who can go to Hell."

Bearing in mind that he was obviously playing a piano on the GnR video for "November Rain", then yes :)

StarSparkle

This is 15 years old and yes I knew he played piano. As Starsparkle says he played it on the November Rain Video.
Now.... slightly more up to date... Is Chinese Democracy ever going to be released? It has been promised every year for the past 4 years at least. It has been 10 years in the making, has he not finished it yet?

and the fact when they turned into the same old boring stadium rock band as the rest, he did his 5 minute piano solo, along with the drum, guitar and bass solos:loopy:
