Today, my son sang our National anthem at the Indians vs. Tigers baseball game.

No - not in the stands with 31,220 other fans, but right behind home-plate on the field.

He wasn't alone. His rich baritone voice was joined with 14 other male and female singers from a show choir in which he performs.

It was an intimidating experience, television cameras a few feet in front of their open mouths and their opening notes were soft and tentative.

But they gained strength and courage from each other - their team - and soon they sang out loud and clear; their harmonies blending superbly.

Each of those singers have a gift all unto themselves and yet they've worked hard to listen closely to each other and blend so that no one voice stands out from the other. I've never heard our National Anthem sound so spectacular.

Think about your own team. The cover article of the June 12, 2006 edition of Fortune, entitled "Secrets of Greatness: Teamwork" talks about the components of a successful team.

Those teams made up of individual superstars are far less likely to be successful than a team made up of talented people working toward a greater good.

How does your team stack up?

Speaking of teamwork: both the Indians and Tigers supported their pitchers with superb team work through the first five innings of today's game (a shut out) until the Tigers pulled ahead to win 4-1.

Bummer.
