Ricky Dineen (born 2 April 1962) is an Irish musician best known as the guitarist with the post-punk band Five Go Down to the Sea?, earlier known as Nun Attax, who later developed into Beethoven–fucking–Beethoven.

were hugely influential on later generations of Irish bands such as The Sultans of Ping FC, and are widely credited for the often quirky and deadpan approach of the 1990s and 2000s Cork scene.

[8] Until then Dineen had been a hard rock and Pink Floyd fan; Donnelly introduced him to post-punk and other groups heard on John Peel's BBC radio show.

[3][9] Nun Attax developed an early live following in Ireland, and in the late 1970s became scene leaders in the punk movement that grew around the Arcadia ballroom, managed by Elvera Butler and Andy Foster.

[10][11] Their local breakthrough came in 1981 when three of their songs were included on the Reekus Records live compilation album Kaught at the Kampus, alongside tracks by Microdisney, Mean Features and Urban Blitz.

[12] They recorded their most acclaimed EP Knot a Fish later that year,[12] which was described in 2001 by Cathal Coughlan of Microdisney and The Fatima Mansions as "just incredible...completely different to Nun Attax...it wasn't like a rock band anymore, it was...bizarre but coherent.

[14] The band went into hiatus in 1985, although Dineen and Donnelly stayed in London and played a number of gigs with a drum machine early in 1986, but without industry interest.

[19] Dineen is currently the music writer and guitarist with Big Boy Foolish, a duo formed with vocalist Liam Heffernan,[20] who self describe as "Post punk Geriatrics".

[24] In 2021 McGrath-Bryan wrote that "unsatisfied with nostalgia, the pair have spent the last number of years cultivating a body of idiosyncratic, drum machine-propelled tunes that sit somewhere to the left of the current wave of genre revivalism.

[19][28][29] The well received compilation album Hiding from the Landlord was released in April 2020, accompanied by a twenty-page fanzine with contributions from Elvira Butler, Cathal Coughlan of Microdisney, Pete Astor of The Weather Prophets, Gavin Friday of the Virgin Prunes, and writers John Robb, Kevin Barry, Declan Lynch and Cónal Creedon.

[10][30] Dineen leads the occasional FGDTTS memorial band And NUN Came Back[19][31] along with vocalist Tom Healy, bassist Humphrey Murphy and drummer Ian Walsh.
