Ed Ames (born Edmund Dantes Urick; July 9, 1927) is an American popular singer and actor. He is known for playing Mingo in the television series Daniel Boone, and for his pop hits of the 1960s including "My Cup Runneth Over", "Who Will Answer?" and "When the Snow is on the Roses". While still in high school, the brothers formed a quartet and often won competitions around the Boston area. Three of the brothers later formed the Amory Brothers quartet and went to New York City, where they were hired by bandleader Art Mooney. Playwright Abe Burrows helped the brothers along the way, suggesting the siblings change their group's name to the Ames Brother n the early 1960s, the Ames Brothers disbanded, and Ed Ames, pursuing a career in acting, studied at the Herbert Berghof School. His first starring role was in an Off Broadway production of Arthur Miller's The Crucible, going on to starring performances in The Fantasticks off-Broadway and Carnival!, which was on Broadway. He was in the national touring company of Carnival Ames' dark complexion and facial bone structure led to his being cast regularly as a Native American. He played Chief Bromden in the Broadway production of One Flew Over the Cuckoo's Nest, opposite Kirk Douglas. Ames played a Mexican bandit on a 1962 The Rifleman episode and guest-starred as Kennedy in the 1963 episode "The Day of the Pawnees, Part 2" on ABC's The Travels of Jaimie McPheeters, with Kurt Russell in the title role. He guest-starred in 1963 on Richard Egan's NBC modern western series, Redigo.

During the 1940s, Ed Ames began performing with his brothers in the singing group, The Ames Brothers before turning his attention to acting. Their first hit was the single, Ragg Mopp. He had a number of Broadway appearances and over 60 television appearances. His Broadway credits include One Flew Over The Cuckoo's Nest, Carnival! and Dracula, Baby. His television credits include The Rifleman, McCloud, Murder, She Wrote and In The Heat Of The Night, as well as numerous talk, game and variety shows including The Ed Sullivan Show, The Merv Griffin Show, The Mike Douglas Show, What's My Line and The Hollywood Squares, but he is best remembered for his role of Native American Indian, Mingo on the Daniel Boone television series. He is also remembered for the infamous hatchet throwing incident on The Tonight With Johnny Carson. As a solo singing artist, he released 25 record albums containing numerous popular hits.

I thought this actor played Tonto on The Lone Ranger as well but I didn't notice that in the description.

Jay Silverheels played Tonto. Unsure if Ames appeared in some episodes.
