Half Drunk Under a Full Moon is the sixth studio album by Scottish rock band the Fratellis.

[6] In contrast to the more rock-oriented music of previous albums, Half Drunk Under a Full Moon features a baroque pop sound with considerable use of brass and strings.

Guitarist and vocalist Jon Fratelli had previously sought this approach on their debut album's most successful single, "Chelsea Dagger": "I wasn't mad keen on going down the road of the chant vocals.

[9] On 2 April 2021, the band released a non-album cover of Baccara's 1977 single "Yes Sir, I Can Boogie" and donated all proceeds to the Tartan Army Children's Charity, Soccer Aid and the Eilidh Brown Memorial Fund.

[10] This was one of two covers released in conjunction with the album, the other being a studio recording of Dion's 1961 single "Runaround Sue" with which the band had been closing concerts for several years.
