I'm confused: is this a trio of Chad Mitchell's, or a group with Chad, Mitchell and Trio in it?
If there's only one Chad, shouldn't it be the Chad Mitchell Duo, or is my maths crap as well?
Well, I googled it and am none the wiser. Chad's trio had a revolving door of singers, but I guess the Chad Mitchell 6-9 isn't as catchy. John Denver did a stint with them, and - you can't make this stuff up - Michael Johnson.
