This is an achievement that Gavin DeGraw will probably never forget.
On Saturday before Game 5 of the first round, the Stanley Cup playoffs series between Nashville Predators and Dallas Stars, the "I Don't Be Be Be Be" singer sang the national anthem before the puck fell.
After the slip-up of the NHL DeGraw confirmed that he was fine.
"I did not know that singing the national anthem is a full-contact sport. #OnOkay: @codyslusher, "wrote DeGraw on Instagram on Saturday.
Unfortunately for the Predators, DeGraw did not bring much luck to the home team when Nashville fell to Dallas 5: 3. The stars are currently leading the series with 3-2.
