Mark Radcliffe played Harry “Haywire Mac” McClintock singing Big Rock Candy Mountain on the Folk Show just last week.

Haywire Mac McClintock also claimed to be the first person to perform The Preacher and the Slave written by Joe Hill, also known as Pie in the Sky, to the tune of In the Sweet By-and-by. He said in an interview with Sam Eskin, recorded in 1951, "You know the ‘Long-haired Preacher Song? Everybody knows that. I had the honor of singing that for the first time in public. Joe brought it in and turned it over to the Secretary of the Portland local of the IWW. He got out a leaflet on it. I think we sold, at the second street meeting — the first street meeting we weren’t prepared, we didn’t have it printed — but the second street meeting we sold over $30 worth of them at a dime a throw or whatever they wanted to contribute."
