There are a few, quite a few in fact, They more or less cover the gauntlet, i've had "Christian Gospel" I've heard "Cowboy Gospel" not that... Was interesting, I've heard straight Country, and I've heard "General Coverage" for want of a better name.
Also hard rock, but that was a local band hired by the park (NOT my cup of tea, If I were to critique the band I would have to say they are not long for the music world and may soon be mutes (unable to speak) But that's what comes from screaming the song instead of singing it)
I like most all kinds of music. I sing mostly church music. And the 20 or so folks I sing with.. Do it well.
