Gotta Let This Hen Out! is a live recording of Robyn Hitchcock and the Egyptians recorded in April 1985, shortly after the group had come together for Fegmania!.

The set was recorded at the Marquee and the tapes cleaned up for release at Alaska Studios with minor drop-in overdubs. The gig was also videotaped and appeared on VHS with a few additional numbers, interspersed with several studio recordings available through their promo videos.

The material selected for this album includes titles ranging through Hitchcock's back catalogue, from Soft Boys songs ("Kingdom Of Love", "The Face Of Death") through his first solo album ("Acid Bird", "Brenda's Iron Sledge") and up to the recently released Fegmania! ("Heaven", "My Wife and My Dead Wife"). The live recording captures the new band just it was defining its sound and fairly documents the highlights of Hitchcock's live set and musical focus in the mid-1980s.

The cover features a painting by Hitchcock depicting airborne fish, jellyfish and an array of ducks and chickens. As with a number of his albums, Hitchcock handwrote the liner notes. The album title is taken from the lyric of the song "Listening to the Higsons", the penultimate track on the album. Hitchcock has stated that this lyric comes from mishearing a Higsons song with the lyric "Gotta let this heat out."

The Midnight CD issue adds "Egyptian Cream", "The Fly", and a staple of his live sets, the Soft Boys' "Only the Stones Remain", as does the 1995 Rhino reissue. The Yep Roc issue adds a further 5 tracks from a June 1989 gig at The Ritz, New York.
