He's got nothing against show-stopping anthem performances like the late Marvin Gaye's at the 1983 NBA All-Star Game in Inglewood, California, or the late Whitney Houston's at the 1991 Super Bowl in Tampa. It's just not his style.
"Sometimes you hear anthem singers sing and it will last three minutes," said Glenn, a tenor. "It's not a hit song, it is an anthem. An anthem means everybody sings, so you try to make it easy so everybody can sing it with you. I'll put a little bit of flair in there, but not too much."
Glenn said he keeps track of other anthem singers around the NHL. He ranks Carnell "Golden Pipes" Johnson, a former singing gondolier at The Venetian in Las Vegas who performs for the Vegas Golden Knights, as his favorite.
"He is fantastic," Glenn said of Johnson. "His power, his pitch, his tone, his energy, it's impeccable. It's all up there."
