Listen to Little Big Town on iHeartRadio

Little Big Town's Karen Fairchild says they had a blast writing their current single, "Day Drinking."  But the country star admits they didn't really know how good the song was until they heard a makeshift demo their co-writers put together. 

The band's Jimi Westbrook adds that he was pretty curious about how the song turned out, because it was so much fun to write. 

"Day Drinking" is the lead-off single from Little Big Town's upcoming album, Painkiller.  The disc is the group's follow up to 2012's "Tornado."  A release date for the project hasn't been announced yet.
