NYT article by Jon Pareles:

Tom Clancy, a founder of the Clancy Brothers folk group and an actor, died yesterday at Mercy Hospital in Cork, Ireland. He was 67 years old.

He died of stomach cancer, his brother Liam said.

Wearing white Aran sweaters and singing rowdy Irish traditional songs for an audience that loved to sing along, the Clancy Brothers and Tommy Makem were a major part of the folk revival of the early 1960's. "What we were doing was very simple," Liam Clancy said yesterday in a telephone interview. "We were singing the old folk songs in a lusty, simple way, and it looked so easy and caught on in such a big way that groups of young fellows all over the world decided to do the same thing -- thousands of groups."

Tom Clancy was born in Carrick-on-Suir in County Tipperary, Ireland. He left school to become a baker when he was 14 and joined the Royal Air Force when he was 17. He flew missions over Germany in World War II. After the war, he joined the Shakespeariana Internationale theater company in Ireland for a short time. In the early 1950's, Tom Clancy and his brother Paddy moved to Toronto and then Cleveland, where they joined the Cleveland Playhouse. From there they moved to New York City, where they were active in Off Broadway theater. Tom Clancy acted on Broadway in the 1958 production of Eugene O'Neill's "Touch of the Poet," with Helen Hayes. 6 Months, 30 Years

Tom Clancy appeared in "King Lear" with Orson Welles and "St. Joan" with Siobhan McKenna. In the mid-1950's, the brothers rented the Cherry Lane Theater in Greenwich Village, and to raise rent money for it they started a series of folk-music concerts. Liam Clancy arrived in 1956, along with Mr. Makem, a friend, and the group recorded folk songs for Tradition Records, a label Paddy Clancy had started.

"We had no intention at that stage of pursuing a singing career," Liam Clancy said, "but the singing became more and more part of our lives." In the late 1950's, Mr. Makem said yesterday, the group decided to try singing for six months before its members returned to "our proper work in the theater."

"But the six months turned into 30 years," he said.

The group was trying to decide on a name -- it considered the Druids, the Bards, the Chieftains and the Moonshiners, among others -- when it arrived for an engagement at the Gate of Horn club in Chicago. On the marquee was "The Clancy Brothers and Tommy Makem."

The group's career took off in the early 1960's. After a stint at the Blue Angel nightclub, the group was booked on "The Ed Sullivan Show" on CBS. At the last minute a headliner became ill, and the Clancy Brothers' 3-minute spot stretched to 18 minutes. Suddenly, Liam Clancy said, "We found ourselves famous." National and international tours followed, including appearances at Carnegie Hall and the Royal Albert Hall in London.

The Clancy Brothers and Tommy Makem were signed to Columbia Records by John Hammond, and they recorded for the label for a decade. They also recorded for Vanguard Records and have made about 50 albums. Although Mr. Makem left the group in 1969 and Liam Clancy left in 1975, the Clancy Brothers (Tom, Paddy and Bobby Clancy and a nephew, Robbie O'Connell) have since toured regularly. Liam Clancy, who rejoined the group last spring when Tom Clancy become ill, said the Clancy Brothers would continue to perform.

In the 1970's and 80's, Tom Clancy also returned to acting. He appeared in television series -- among them "The Incredible Hulk," "Charlie's Angels" and "Little House on the Prairie."


In addition to his brothers, he is survived by his wife, Blawnin; two daughters, Raylin and Cait; and four sisters, Lili, Joan, Peg and Leish.
