Backstaging it up over a very musical weekend ...

Backstreet Boys: So what we didn't know at Saturday's Backstreet Boys concert was what the heck those eight huge motor coaches were doing parked behind Firstar Centre. A limo driver filled us in.

Turns out each of the five Boys has his own $1.2 million custom coach for privacy on the road. Watch their own videos, listen to their own music, entertain in private, that sort of thing.

The other three are for guests. Sometimes moms join the tour. Sometimes friends. They all get their own coaches.

Very hospitable, these lads.
