I just got a shock as I learned of the death of Irish singer and musician (flute and uileann pipes) Meaití Jo Shéamuis Ó Fátharta of Conamara. He was a lovely cordial man, as well as being a fine musician. He was a radio presenter and collector as well; I just read that in 2021 Meaití (Matty) donated his collected resources to the Irish Traditional Music Archives.

Meaití Jo Shémais won the celebrated Corn uí Riada for sean-nós singers in 2001.

I didn't find videos of Meaití Jo Shéamais playing music, only of him singing and lilting.
