The show was aimed at raising awareness for Laliberte's One Drop Foundation, which seeks to draw attention to the growing shortage of clean water.

One of the most anticipated segments of the evening was a chat between Laliberte and Bono, who was performing with U2 at a concert in Tampa, Florida.

"You are the first clown in space and we think it's a great idea for you to give us your perspective on our little planet while you're not on our little planet and instead looking down on it," Bono said. "How do we look from there, how does our little planet look, Guy?"

Laliberte replied that "planet Earth looks so great but also so fragile."

The event combined live and taped segments. Production costs for the multilingual show are estimated at between $6 million and $10 million — which is on top of the $35 million Laliberte paid to become Canada's first space tourist.

It was seen on the Internet beginning at 8 p.m EDT; 0000 GMT through the One Drop Foundation's Web site: www.onedrop.org.
