3 Redneck Tenors

Okay, I'm split on this one.  This morning I saw the commercial for the Three Redneck Tenors.  http://www.3rednecktenors.com/ ; for their site.  They're performing at the Hippodome this weekend... and I'm wondering if I should go.

The thing is... they sound really good in the commercial.  But that means they may just suck because I've seen many cases in which the commercial was better than the advertised product (especially in movies).

Maus?  Got a take on this?
