I played in a bluegrass band where the Dobro player was named Reg Buck. We called ourselves "Buck & Loose Change".

Another roots band was called "Late For Dinner". We said, "You can't call us anything, but you can all us Late For Dinner."

Right now I play in a jug band. One of our members' father played in a dance band called the Merry Land Collegians and they had black velvet music stand banners with MLC embroidered in gold. We used one of those banners and called ourselves the MLC JUg Band for our first couple of gigs. We asked the audience to try to think up a good name for the band. They came up with some interesting ideas: "Mamma's Little Cuties", "Meat & Livestock Commission", "Misery Loves Company" and a dozen or so others.
We finally decided on The Maple Leaf Champions Jug Band, since there hadn't been any Maple Leaf Champions since 1967.
