Macy Gray's performance on the "Today" show was supposed to include a Brittney Grinerprotest ... but the singer and her keyboardist says network honchos wouldn't let it happen.
Billy Wes arrived at NBC Studios in New York City on Thursday morning rocking a black tee shirt with bold white letters reading, "FREE BRITNEY GRINER" ... but when he was on-air, the message was mysteriously hidden.
We asked Milly what happened after the show ... and he told us "Today" honchos told him he couldn't wear the shirt and made him turn it inside out. Macy stopped to talk to us, saying Brittney's situation is really a sad one, and says the plan was for Wes to wear the shirt.
Milly wouldn't tell our camera what explanation he was given as to why he couldn't wear the shirt on-air ... but you can tell he was bummed out.
