It may not be the regular season yet, but Illinois quarterbacks Reilly O'Toole and Wes Lunt were in mid-season form -- with their singing voices.

While warming up for the spring game, O'Toole and Lunt engaged in a sing-along to the Backstreet Boys' classic hit "I Want It That Way" that was playing on the stadium's speakers.

A crowd of more than 5,000 people attended the spring game, though most missed out on the special pre-game concert.
