Canyon? Am I being dense again?

Wiz, "canyon" is a homophone for "Kenyan".

I did think about that..but sounded wrong "a" not "e" in my way of speaking.

Yeah, the accent can be tricky.

Fun, but problematic. Should be "Peace of Mind" rather than "Piece of Mind" perhaps? would not accept partners for the TV group.

"Piece of mind" exists as an idiom, as in give someone a piece of your mind. It sounds identical, but is an entirely different idiom.
And yes, maybe I should have included partners in the acceptable answers.

"Piece of Mind" is also more importantly (IMHO) an album by Iron Maiden! ;)

For the Dale group, tried synonyms of gorge or glen (couldn't think of further examples... and while I realise this doesn't quite fit with "trench", I struggled for a different way to encapsulate the group!). I also agree "Canyon" could be seen as a little tenuous as a homophone of "Kenyan" but again that could be just down to my multifarious accent ;)

hmmmm.... it's "piece of my mind" or "peace of mind" not "piece of mind".... I'm also not convinced canyon is a homophoe of Kenyan but.... ok
