Dear Rood End Band,

I am writing to offer my heartfelt and unreserved apology for the deeply inappropriate and offensive comments I made, in which I wrongly associated your name with the use of the N-word.
My words were completely unacceptable, and I take full responsibility for the harm they have caused.
I now understand the seriousness of my actions and the pain they may have inflicted on you as individuals and as a group.
It was wrong of me to involve your name in any such context, and I want to make it absolutely clear that you had no part in what was said.
I deeply regret the disrespect and damage my statement may have caused to your reputation. I am committed to learning from this, listening, and doing better going forward.
Please accept my sincere apologies.

With regret,
Oswald
