Question:
Daniel Lee Dierdorf (born June 29, 1949) is a former American football offensive lineman and current sportscaster. A native of Canton, Ohio, Dierdorf played college football for the University of Michigan from 1968 to 1970 and was selected as a consensus first-team All-American in 1970 and a first-team All-Big Ten Conference player in 1969 and 1970. He was inducted into the University of Michigan Athletic Hall of Honor in 1996 and the College Football Hall of Fame in 2000. Dierdorf played professional football in National Football League (NFL) with the St. Louis Cardinals for 13 seasons from 1971 to 1983.
On September 9, 1979, Dierforf sustained torn ligaments in his left knee during an extra point attempt in the second quarter of the second game of the season against the New York Giants. After the game, Dierdorf said, "The knee was completely out of the socket. It moved a couple of inches off to the side. My leg was all twisted around and my foot was pointing in the wrong direction. It was painful. Very painful." Dierdorf was carried off the field on a stretcher, underwent knee surgery, and missed the remainder of the 1979 season. Dierdorf returned to the Cardinals in 1980, starting all 16 games for the team at right tackle in both the 1980 and 1981 seasons. In 1980, he was selected to play in the Pro Bowl and was selected as a first-team All-NFL player by the NEA. In 1982, Dierdorf moved to center and was the starter at that position for all nine games in a strike-shortened season. In 1983, Dierdorf returned to his right tackle position and appeared in seven games, only four as a starter. On October 11, 1983, after the Cardinals began the season with a 1-5 record, Dierdorf announced that he would retire at the end of the 1983 season. At the press conference announcing his retirement, Dierdorf said, "This was an easy decision for me to make. . . . Physically, I just can't play the type of game I want to." He added: "Ninety-five percent of me is sad that I'm retiring, but my knees are very, very happy."

input: In 2009, the band again worked with producer Bob Rock, and We Are the Same was released in North America on April 7, 2009. It produced three singles. To promote We Are the Same, the band invited The Hour's George Stroumboulopoulos for a live interview at The Bathouse Recording Studio in Bath, Ontario (where most of the album was recorded), and they played seven new songs as well as unique versions of five other songs. The interview and performance were broadcast live in more than eighty theatres across Canada. On January 22, 2010, the band performed "Fiddler's Green" at the "Canada for Haiti" telethon to aid earthquake victims in that country. This was broadcast nationally on all three of Canada's main networks (CBC, Global, and CTV). On May 12, 2012, a 90-second clip of the song "At Transformation", the first single from the band's new album, premiered during Hockey Night in Canada. The full song premiered on Toronto radio station CFNY-FM (102.1 The Edge) on May 16. The song was released to radio stations on May 17 and was officially released on iTunes on May 18. Band member Johnny Fay revealed that the title for the album is Now for Plan A. The second single, "Streets Ahead," was released on August 24.

Answer the question at the end by quoting:

Muddy Waters' birthplace and date are not conclusively known. He stated that he was born in Rolling Fork, Mississippi, in 1915, but it is believed to be more likely that he was born in Jug's Corner, in neighboring Issaquena County, in 1913. Recent research has uncovered documentation showing that in the 1930s and 1940s, before his rise to fame, the year of his birth was reported as 1913 on his marriage license, recording notes, and musicians' union card. A 1955 interview in the Chicago Defender is the earliest in which he stated 1915 as the year of his birth, and he continued to say this in interviews from that point onward.
In August 1941, Alan Lomax went to Stovall, Mississippi, on behalf of the Library of Congress to record various country blues musicians. "He brought his stuff down and recorded me right in my house," Muddy recalled for Rolling Stone magazine, "and when he played back the first song I sounded just like anybody's records. Man, you don't know how I felt that Saturday afternoon when I heard that voice and it was my own voice. Later on he sent me two copies of the pressing and a check for twenty bucks, and I carried that record up to the corner and put it on the jukebox. Just played it and played it and said, 'I can do it, I can do it.'" Lomax came back in July 1942 to record him again. Both sessions were eventually released by Testament Records as Down on Stovall's Plantation. The complete recordings were reissued by Chess Records on CD as Muddy Waters: The Complete Plantation Recordings. The Historic 1941-42 Library of Congress Field Recordings in 1993 and remastered in 1997. In 1943, Muddy Waters headed to Chicago with the hope of becoming a full-time professional musician. He lived with a relative for a short period while driving a truck and working in a factory by day and performing at night. Big Bill Broonzy, then one of the leading bluesmen in Chicago, had Muddy Waters open his shows in the rowdy clubs where Broonzy played. This gave Muddy Waters the opportunity to play in front of a large audience. In 1944, he bought his first electric guitar and then formed his first electric combo. He felt obliged to electrify his sound in Chicago because, he said, "When I went into the clubs, the first thing I wanted was an amplifier. Couldn't nobody hear you with an acoustic." His sound reflected the optimism of postwar African Americans. Willie Dixon said that "There was quite a few people around singing the blues but most of them was singing all sad blues. Muddy was giving his blues a little pep." Three years later, in 1946, he recorded some songs for Mayo Williams at Columbia Records, with an old-fashioned combo consisting of clarinet, saxophone and piano; they were released a year later with Ivan Ballen's Philadelphia-based 20th Century label, billed as James "Sweet Lucy" Carter and his Orchestra - Muddy Waters' name was not mentioned on the label. Later that year, he began recording for Aristocrat Records, a newly formed label run by the brothers Leonard and Phil Chess. In 1947, he played guitar with Sunnyland Slim on piano on the cuts "Gypsy Woman" and "Little Anna Mae". These were also shelved, but in 1948, "I Can't Be Satisfied" and "I Feel Like Going Home" became hits, and his popularity in clubs began to take off. Soon after, Aristocrat changed its name to Chess Records. Muddy Waters's signature tune "Rollin' Stone" also became a hit that year.
