Lee Brice and his wife may be expecting a baby girl this summer, but the cool crooner’s “Boy” is due first.

Lee’s new single, “Boy,” ships to country radio this week. The nostalgic tune, which is the lead single from Lee’s upcoming fourth studio album, celebrates the many “firsts” in a boy’s life, including first fight, first kiss, first heartbreak and more.

Lee headlined a show last night (May 17) at Nashville’s 3rd & Lindsley as part of Nash Icon’s Rhythm and Boots concert series to benefit Musicians On Call. In front of the sold-out crowd, Lee treated fans to a number of songs from his catalog, including “Drinking Class” and his first single, “She Ain’t Right,” but the the most poignant moment came when Lee performed a stripped-down version of his upcoming single, “Boy.”

Watch Lee’s acoustic rendition of “Boy” below.
