Listen to this interview with Mr. Daniel Handler on NPR's Fresh Air to hear him play an accordion song written specifically for his new book, Who Could That Be at This Hour?, by Stephin Merritt. Mr. Merritt briefly mentions the song's origins in this interview. Mr. Handler has been playing the song on his Lemony Snicket book tour, as can be evidenced here. Many thanks to Aimi Hamraie for the NPR link.
Also, Mr. Merritt will appear on Soundcheck this Thursday December 13 at 9:00pm EST. He and Amy Regan will be interviewing musician Beck before Mr. Merritt plays one of Beck's new songs. More information can be found here. I will, unfortunately, be otherwise indisposed during the broadcast, so if anyone wants to record it for me or anything, that would be lovely.
