Steven Tyler is standing up for songwriters.

He spent his visit this week to Washington meeting with members of Congress to talk about stronger protection for songwriters in the copyright system, including against having their work used in samples or mashups by other artists.

Then he rocked a concert last night in Washington, D.C., according to washingtonpost.com:

Onstage, with a view of the Capitol in the background, Tyler capped off a few days of lobbying with renditions of hits like “Cryin’” and “Dream On,” to a crowd of suits who looked like they were reliving their high-school days.

And by the way, happy birthday to Steven, who turns 65 years old today, born on March 26th, 1948 in Yonkers, New York.
