Mumford & Sons Release Their Newest Single, “If I Say” Mumford & Sons have released “If I Say,” the second single off their highly anticipated upcoming album Delta, out November 16. Like “Guiding Light,” the message behind “If I Say” is easy to get behind. “And if I say I love you / Then I love you,” Marcus Mumford affirms, over an stirring string arrangement. It’s the musical consolation everyone deserves to receive, especially right now. Make sure to pre-order Delta and catch Mumford & Sons on their first tour in five years.
