Hungry Heart

Got a wife and kids in Baltimore, Jack
I went out for a ride and I never went back
Like a river that don't know where it's flowing
I took a wrong turn and I just kept going

Everybody's got a hungry heart
Everybody's got a hungry heart
Lay down your money and you play your part
Everybody's got a h-h-hungry heart 

C’mon!!!

Brue Springsteen famously encourages the audience to sing the first verse and chorus to Hungry Heart in his concerts.  https://www.youtube.com/watch?v=OZwKijVuv5I.  

Audra McDonald encouraged the audience at the London Palladium to join in the song I Could Have Danced All Night.  https://www.youtube.com/watch?v=3orzNvj2yfg. 

Kermit the Frog led the audience of Choir,  Choir, Choir, in singing the Rainbow Connection at the Lincoln Center. https://www.youtube.com/watch?v=uKphuLqr1mI

In each of these the singer could have merely performed the song for the audience.  The singer led the audience in becoming the song.  The best leaders lead the group, they do not lead for the group.  Become the song, and in doing so become the group.
