Mark Haines (April 19, 1946 – May 24, 2011) was a host on the CNBC television network.

Haines grew up in Oyster Bay, New York, and resided in Monmouth County, New Jersey. His alma mater was Denison University, and in 1989, the University of Pennsylvania Law School. He was a member of the New Jersey bar association.

Haines was a news anchor for KYW-TV in Philadelphia, Pennsylvania; WABC-TV in New York City; and WPRI-TV in Providence, Rhode Island. It is reported that Cary Grant considered Haines his favorite television reporter.

In 1989, Haines joined the newly created CNBC network. Haines was the host of the CNBC TV shows Squawk Box and Squawk on the Street. Haines was on the air when news of the September 11 attacks first broke in 2001 [1]. Squawk on the Street was expanded from one hour to two on July 19, 2007, when co-anchor Liz Claman of Morning Call left to co-anchor Fox Business on the Fox Business Network. Haines also presented a financial segment prior to the market open each day on MSNBC's Morning Joe.

Peter "Pete" Seeger (born May 3, 1919) is an American folk singer and an iconic figure in the mid-20th-century American folk music revival. A fixture on nationwide radio in the 1940s, he also had a string of hit records during the early 1950s as a member of The Weavers, most notably their recording of Lead Belly's "Goodnight, Irene", which topped the charts for 13 weeks in 1950. Members of The Weavers were blacklisted during the McCarthy Era. In the 1960s, he re-emerged on the public scene as a prominent singer of protest music in support of international disarmament, civil rights, and environmental causes.

As a song writer, he is best known as the author or co-author of "Where Have All the Flowers Gone?", "If I Had a Hammer (The Hammer Song)", (composed with Lee Hays of The Weavers), and "Turn, Turn, Turn!", which have been recorded by many artists both in and outside the folk revival movement and are still sung throughout the world. "Flowers" was a hit recording for The Kingston Trio (1962); Marlene Dietrich, who recorded it in English, German and French (1962); and Johnny Rivers (1965). "If I Had a Hammer" was a hit for Peter, Paul & Mary (1962) and Trini Lopez (1963), while The Byrds popularized "Turn, Turn, Turn!" in the mid-1960s, as did Judy Collins in 1964, and The Seekers in 1966. Seeger was one of the folksingers most responsible for popularizing the spiritual "We Shall Overcome" (also recorded by Joan Baez and many other singer-activists) that became the acknowledged anthem of the 1960s American Civil Rights Movement, soon after folk singer and activist Guy Carawan introduced it at the founding meeting of the Student Nonviolent Coordinating Committee (SNCC) in 1960. In the PBS "American Masters" episode Pete Seeger: The Power of Song, Seeger states it was he who changed the lyric from the traditional "We will overcome" to the more singable "We shall overcome".
