Song from talkshow (should be easy)
 

So, I was watching this old interview of Amanda Seyfried yesterday. And the song they played as she walked in was so nice, but I hadn't any luck finding out who it was. I mailed CBS and they couldn't help me, so now I need your expertise

Since I'm new I can't post links, but search for
"Amanda Seyfried on The Late Late Show with Craig Ferguson" on youtube and the song should start around 0:40

It sounds so familiar, right?
