Techno song "I can't live without you"

It was in a car commercial back in 2002 and I don't know what song it is can anyone help? And theres also a song on another car commercial currently airing now by Jeep timeline. The lyrics are "I'm having the time of my life Oaa". And one more song I don't know and again it's a car commercial with a snow storm and the lyrics are "Baby, it's cold outside" I think it's Nat king Cole but I could be wrong.

First one: Paul van Dyk feat Vega 4 - Time of our Lives

Ha, That's the second one. Thanks!

The second song?

Maybe Dean Martin?
Because Lexus had some commercial, where the car is in snow or in tundra (or some similar place), and the song sounds like this: http://www.youtube.com/watch?v=8PbPPhkoiWs

Actually that was another song I was looking for but it was a different version on a different snowy car commercial within the past few months. The song "I can't live without out you" was a car commercial in a city at night time. I also found the funny version of a grand old flag, it was by Bill Murray.
