"Play that Song again Bud"

"he says..Son can you play me a memory...
Im not really sure how it goes...
But its sad and its sweet,
And i knew it complete...
When i wore a younger mans clothes"

Sing us a song youre the Piano man...
Sing us a song tonight,
Well were all in the mood for a melody,
And youve got us feeling alright"

Billy Joel.
