Singer-songwriter Aimee Mann is better known for her melancholy tunes, but she’s filled with (partial) cheer at least once a year.Her sixth annual Aimee Mann Christmas Show is a variety show with a crack supporting cast of musicians, comedians and other special guests that stops at the Wiltern on Dec. 10. Past guests have included John C. Reilly, Jeff Goldblum, John Krasinski, Zooey Deschanel and Will Ferrell. Michael Penn, Paul F. Thompkins, Tim Heidecker, Nellie McKay and Andy Daly are just some of the guests booked for this year’s yuletide extravaganza. Mann performs a variety of songs from her repertoire, including the new tune “Charmer” from her forthcoming album, but is sure to pull material from her untraditional 2006 Christmas album, One More Drifter in the Snow.
