With the 104th Grey Cup less than three months away, the finer details are being ironed out, including the halftime act for the game at BMO Field on Nov. 27.

While he didn’t want to divulge specifics, Paulo Senra, the CFL’s director of communications, said an act has been booked and it’s one fans will know well.

“The act that’s coming is on the list of the top-40 most-viewed music videos on YouTube,” Senra said on Monday.

He also mentioned bands on the list that have more than one billion views, which cuts the list down to 30. For better or worse, depending on your musical tastes, that has Toronto-based band Magic just making the cut.

The door is still wide open tough, but a few notable names pop up, including Wiz Khalifa, Mark Ronson, Justin Bieber, Taylor Swift, Katy Perry and Adele. It would be safe to rule out Adele, though, as she recently shot down the idea of playing the coveted halftime show at the Super Bowl in Houston.

Meghan Trainor, OneRepublic, Sia, Ed Sheeran, Elie Goulding, Shakira and Eminem are a few of the other names on the list.

The CFL has opened its doors to a mix of Canadian and American artists as halftime acts since 2005, when the Black Eyed Peas played the 93rd Grey Cup in Vancouver. Since then, Toronto has hosted the event twice, bringing in Lenny Kravitz in 2007 and a string of Canadian talent in 2012 that included Bieber, Carly Rae Jepsen, Marianas Trench and Gordon Lightfoot.

American rock band Fallout Boy performed at halftime of last year’s Grey Cup in Winnipeg.

The league will make an official announcement on this year’s halftime act Wednesday.
