TIL in late 60s a group of imposters from Texas pretended to be the British rock band the Zombies and toured throughout the U.S to sold out shows. Two of those imposters (Dusty Hill and Frank Beard) would go on to form ZZ Top.

*The Zombies, unaware of their stateside success — this was possible in 1969 — had already moved on to new musical projects or day jobs. This vacuum meant anyone could tour the United States pretending to be the Zombies, even a four-piece blues band from Dallas.*
*There were in fact two different bands touring the United States in 1969 calling themselves the Zombies. Both impostor groups were managed by the same company, Delta Promotions, the owners of which insisted they’d legally acquired the songs of the Zombies and other bands. It was an operation that would be impossible to attempt today, perpetrated in an era when fans didn’t have unlimited access to artists’ whereabouts, or, in some cases, even know what they looked like.*
*It was in this climate that Delta Promotions took this exploitation to a new extreme, figuring out a way to tour and sell “the Zombies” and other bands without those bands or their fans even realizing. As the British Invasion spurred rock’s cultural explosion in the ’60s, there simply weren’t yet enough of these upstart bands touring North America to meet the demand. So they made some up.*
