Example Input: Question: How many years had the Astor Hotel been in business the year that Ciampa scaled the exterior of it? Passage:A bricklayer by profession, Ciampa also worked in the entertainment business throughout the late 1940s and early 1950s, starring in Larry Sunbrock's Rodeo and Thrill Circus in New York City and then traveling with the circus to various U.S. and Canadian cities. Notably, his act did not include the typical, tightly choreographed feats of circus acrobatics such as trapeze swinging or trampolining, but rather improvised climbing and leaping stunts making use of scaffolding and circus rigging. Spectators were frequently alarmed by the apparently ad libbed and obviously dangerous nature of his performances. In 1947 Ciampa was arrested for having scaled the exterior of the Astor Hotel as a publicity stunt for the Sunbrock Circus, concerning onlookers who feared that he might have been attempting suicide.

He then was a basketball announcer for his alma mater, the University of Kansas, for one year, then went on to call games for the NFL's Kansas City Chiefs from 1985–93 after several years hosting and producing surrounding pre-game and post-game programming (coincidentally, current Packers play-by-play voice Wayne Larrivee left the Chiefs position open when he began a thirteen-year run as the voice of the Chicago Bears). Harlan also split time with the University of Missouri (1986–89) calling football and basketball games, and worked as the play-by-play voice of the NBA's Minnesota Timberwolves for nine seasons (1989–98). On the network level, Harlan called NFL football for NBC in 1991, college football for ESPN in 1992–93, NFL for Fox from 1994–97, and joined Turner Sports in 1996 to cover NBA playoff games (he would begin calling games throughout the entire season in 1997, which he continues to do to this day). He began working for CBS in 1998.
