Danny Trejo, Steve Buscemi and Iwan Rheon transcend tough-guy roles, sing sweet Red Nose Day song

LOS ANGELES, May 27 (UPI) -- Danny Trejo, Steve Buscemi and Iwan Rheon lampooned their tough-guy personas on Thursday's Red Nose Day telethon.

Their pre-taped music video started off with Trejo telling show staffers he wanted to help out, only to be informed they don't strong-arm people into donating money and, therefore, won't need his assistance.

The Machete star then launches into a ballad and is joined by Rheon, who is best known for playing the cruel nobleman Ramsay Bolton on Game of Thrones.

"People think I'm scary, but I'm gentle as a baby duck. I'm not really mean. I just happen to look that way. Why can't I be a part of Red Nose Day?" sing Rheon, as he plants flowers, and Trejo as he attempts to make friends.

Buscemi, sitting on a carousal horse, chimes in a few moments later, "I sometimes act the guy who kills people and robs banks, but in real life I'm actually nicer than Tom Hanks."

NBC's 2-hour musical and comedy program, which also included celebrity testimonials, was hosted by Craig Ferguson. Blake Shelton and Elton John were among the evening's musical performers.

This year's campaign raised $30.7 million for children in poverty around the world.
