The Alferd Packer Memorial String Bang can be called all of those things. They get us boogying with “Rural Road Rhythm,” have us filled with puns and laughter with their Science Song, and (for decades) have spooked us with “Send Me To Glory In A Glad Bag.” They’ve spent so many years winning over audiences with that song, it’s finally celebrating an anniversary.

The Glad Bag song was written 40 years ago, and the band will be celebrating with a party at the Jackpot Saloon on Saturday, November 7th, from 7:00 p.m. to 9:00 p.m.

John Biggs was the first one to record the song in 1978, and his version made it to the Dr. Demento Show. He’ll be performing, along with Kansas City Hustle. The special event will feature a performance by the Alferd Packer Memorial String Band, along with several guest musicians singing verses on the Glad Bag song.

The band made a special Facebook page to commemorate the song and detail all the festivities. You can watch a clip of the song below, as it was performed at one of the many (now defunct) tax day parties at the post office.
