Mícheál Ó Súilleabháin says he's not THE Mícheál Ó Súilleabháin in question, who was a W Cork poet. So he couldn't give me any more information than that. Given that Seán Ó Riada was also cited, it was a logical connection for me to make - two men whose careers almost overlapped (Ó Riada was only 40 years old when he died in 1971) and both known for linking classical and traditional music. But it turns out the connection was wrong.
