'Last Name' is the third single from Carrie Underwood's second studio album, 'Carnival Ride.' Released in 2008, the song hit No. 1 on the Billboard Hot Country Songs chart and won a Grammy, a People's Choice Award and a BMI Award. The tune was co-written by Luke Laird, Hillary Lindsey and Underwood. Below, Laird shares the story behind the song.

We wrote 'Last Name' in January of 2007. My manager, Chris Oglesby, set up the co-write with Carrie, Hillary Lindsey and myself. Hillary is one of my best friends, so we had written many songs together.

The three of us had already written one song that day. Then Carrie was telling us about meeting some guy at a post-Oscar party. The guy got her number, but when he called her, she realized she didn't even know his last name. He called her a couple of times, but she said it was past the point of her asking him his last name.

Anyway, when Carrie told us that story, we all just ran with "last name" and came up with a fun storyline. Very fun day! We laughed a lot.

Side note: We wrote this two days after we wrote 'So Small.' Productive week!
