Iconic porn star Ron Jeremy, who once got a key to Las Vegas from Las Vegas Mayor Oscar Goodman and lamented it was only 6 inches long, is having a unique encore performance in Las Vegas this weekend: making music! 
Jeremy, who grew up playing piano and violin, will play a little harmonica introduction for Sin City Sinners at Boulder Station tonight (10 p.m., free) and at Green Valley Ranch on Saturday (11 p.m., free).
Jeremy has shot many feature films in Las Vegas — boasting he has had sex with somewhere between 4,000 and 5,000 women — remains the most mainstreamed porn legend of all time, not just consulting on “91/2 weeks” and “Boogie Nights” but appearing in music videos, the TV show “The Surreal Life” and a film, this year’s “Crank: High Voltage,” in addition to penning “Ron Jeremy: The Hardest (Working) Man in Showbiz.”
