Luke's song�the title track and first single from the ACM Entertainer of the Year's upcoming album, due Aug. 13�is an upbeat, summer-friendly tune that's somewhere between a love song and a booty call.

The lyrics aren't about any soiree in particular; instead, his message is simply that the "party" can take place anywhere, and it can start anytime.

"If it's 2 in the morning and you're feeling lonely and wondering what I'm doing," he sings, "go ahead and call me." And never mind if it's "in the dead of the night," he's willing to "break [his] plans," so "swing on by" and he'll "pour you a drink." Oh, and "the door's unlocked" and he'll "leave on the lights."
