I've recently come across a new cover band that I wasn't aware of yet, similar to The Classic Rock Show. They're called Hindley Street Country Club and they're from Australia. Unlike what their name suggests, their work includes covers from all kinds of musical styles, and just as with The Classic Rock Show, their lineup has changed a lot over time. One major difference with The Classic Rock Show is that HSCC also modifies the arrangements a bit to insert a jazzy touch into their versions of the songs.
They also on occasion bring in some talent from outside of the band, such as in the performance below. The "guest" in this case is Lesley Williams ─ wearing the pink dress. She's muchas hot, by the way.
