Number of Coming Acts, 3. Average age, 52.

Our shiny new radial tire in downtown, the Sprint Center, is set to open for some seriously aging stars. And no, we’re not talking the Chiefs. The headliners include Van Halen, Elton John and, now, Garth Brooks. To help put some perspective on these aging showmen, here’s a look at their careers:

Elton John

Age: 60

First hit: “Your Song” in 1970

Last hit: “Answer in the Sky” in 2005

Lowest point: There’s many, but in 1997, for his 50th birthday party, Sir Elton performed in an $80,000 Louis XIV costume

Second job: Agreed in 2001 to appear on a BBC’s quiz show but backed out hours before filming and was replaced with a cab driver who worked as an Elton John impersonator
