"I Can't Sleep" is a song co-written and recorded by American country music singer Clay Walker.

Not long after that, Chely Wright and Lonestar's Richie McDonald came on my bus at a show in Colorado and we played songs we'd each started writing.

"[1] Wright told Jam!, "The most creative thing happened the other night when we were in Colorado and Clay Walker was on the show as well.

I popped up on his bus to say hi ... we got to talkin' about songs and we passed the guitar back and forth a couple of times and played some new stuff we'd written.

Mandy Davis of the St. Louis Post-Dispatch commented in her review of "A Few Questions", "On "I Can't Sleep," you can almost hear Walker pleading for the crossover success of Garth Brooks or Tim McGraw.".

[4] In regards to the video's filming location, Walker stated, "If anyone has any doubt as to what life would be like without the freedoms and liberties granted to us in America, I suggest they spend a little time in a Communist country like Cuba.
