We told you about this when it was announced, but tonight's the night that actor Alan Cumming brings his one-man cabaret act, Alan Cumming Sings Sappy Songs, to the Castro Theater, and there are still tickets to be had.

The show blends an eclectic mix of songs both from pop and musical theater genres, including covers of Billy Joel and Rufus Wainwright as well as a Katy Perry-Lady Gaga-Adele medley called "Someone Like the Edge of Fireworks," and a wittily mashed-up Sondheim medley called "No One Is Alive While I’m Around."

He's also recorded an album of the show, which originally premiered at the Cafe Carlyle in New York, and you can find that on iTunes.

Tickets for tonight's show, which starts at 8 p.m., start at $35.
