The Baltimore Sun is advising all Eddie Vedder fans to keep their cars gassed up because tonight, this whole Hannan-at-the-Vedder-shows thing may be working in reverse.

I have it on good authority that grunge icon Eddie Vedder will make a guest appearance at The 8x10tonight to sit in with Jerry Hannan and the Decades.
Vedder is in town as part of his solo tour, and will perform a second night at the Lyric Opera House tonight. He and Hannan recorded the critically acclaimed song "Society" together for Sean Penn's 2007 film Into the Wild.
In fact, I hear that Hannan is going to sit in with Vedder at the Lyric, and then Vedder is headed to South Baltimore for a song or two with Hannan.
