My partner grew up in Billings, so I've had the good fortune to visit the Crystal twice for a song and a drink. On my last visit the KJ actually recorded my song and gave me a buy 1 get 1 free drink ticket. Holy Cow! Back in my hometown you sometimes have to pay to sing, or at least tip the KJ so they don't bump you to the bottom of the queue. Anyway, I think this place is pretty funky. You can buy popcorn and get various flavors of special salt/butter to top it with. The server was cute and very nice, the singers range from the terrible to the amazing, so it's low-pressure and always a good time.
The guy who told me I sounded like I was opera-singing on "Crazy On You" kind of embarrassed me, but whatever. I'll take opera over awful any day.
