Henry McCullough, who played guitar in Paul McCartney’s band Wings, has died. He was 72.

His live music agent Nigel Martyn said McCullough died Tuesday after a long illness. He said the guitarist never fully recovered from a severe heart attack suffered four years ago.

McCullough played with the Grease Band with Joe Cocker at Woodstock, and worked at various times with Marianne Faithfull and Donovan, and he also appeared on the original cast recording of Jesus Christ Superstar.

The Northern Ireland native was recruited to join the second version of Wings in 1971, and his guitar solo on My Girl on the album Red Rose Speedway marked a career peak. He improvised it in a single take.

He left Wings in 1973 after clashing with McCartney.
