John Mark Ainsley

John Mark Ainsley (born 1963) is a singer, known for his performances of baroque music and opera.

He was born in Crewe and educated at Worcester and Magdalen College Oxford.

In 2007 he had a civil partnership with the organist William Whitehead.

He was listed in the Pink List 2000. The citation said:
 * "Ainsley is one of the great modern tenors and, at 37, one of the youngest. Had he been Italian, he would be feted like Pavarotti. Last night he appeared in Salzburg, but is a regular in many of the great houses as well as a leading recording artist."
