McGavock Dickinson Gayden was an American rock and country singer, songwriter, musician, and record producer working in Nashville during the latter half of the 20th century. As a session guitarist, Gayden was featured on Bob Dylan's album Blonde On Blonde, but was inadvertently left off the album's credits. He co-wrote "Everlasting Love", his most successful song. It became an enduring hit, recorded by other artists at least two dozen times over a 60 year span and achieved top-40 status worldwide. He was president of Wild Child Records, formed in 2004. In 2013, he was honored by the Country Music Hall of Fame as one of the "Nashville Cats".
