The Táin was released in Ireland in 1973 independently, in the UK by RCA/Oats and by Atco in the US. It was reissued in the UK in 1978 by DJM.
"Dearg Doom" was arguably the most popular track on the album and was included in Tom Dunne's 30 Best Irish Hits compilation, released in 2003. Along with "Faster Than The Hound", it was performed by the band on BBC's Old Grey Whistle Test. "Dearg Doom's" main guitar riff was incorporated into "Put 'Em Under Pressure", the anthem of the Republic of Ireland's Italia '90 campaign, reintroducing the song to a younger audience.
