The Irish Pub story in the October ANALOG featured a friendly rivalry between two patrons over the best rendition of the four-part, close-harmony song "Mr. Sandman."
The song was of course connected to the core story about silicon-based life.

and the cover by Pomplamoose, which is cutely done. Song ends about 2:20 and the rest is talking head stuff.
