input: Aykroyd was a close friend of John Belushi. According to Aykroyd, it was their first meeting that helped spark the Blues Brothers act. When they met in a club Aykroyd frequented, he played a blues record in the background, and it stimulated a fascination with blues in Belushi, who was primarily a fan of heavy rock bands at the time. Aykroyd educated Belushi on the finer points of blues music and, with a little encouragement from then-SNL music director Paul Shaffer, it led to the creation of their Blues Brothers characters.  Backed by such experienced professional R&B sidemen as lead guitarist Steve Cropper, sax man Lou Marini, trumpeter Alan Rubin and bass guitarist Donald "Duck" Dunn, the Blues Brothers proved more than an SNL novelty. Taking off with the public as a legitimate musical act, they performed live gigs and in 1978 released the hit album Briefcase Full of Blues (drawn from the fact that Aykroyd, as "Elwood Blues", carried his blues harmonicas in a briefcase that he kept handcuffed to his wrist, in the manner of a CIA courier; Belushi originally carried the key to those handcuffs). Briefcase Full of Blues eventually sold 3.5 million copies, and is one of the highest-selling blues albums of all time. The band was much further popularized in the 1980 film The Blues Brothers, which Aykroyd co-wrote.  Early in the incarnation of the Blues Brothers, Belushi joined the Grateful Dead on stage on April 2, 1980, for a rendition of "Good Morning Little School Girl" at the Capitol Theatre in Passaic, New Jersey that coincided with the Dead's appearance on SNL that weekend. Belushi sang the part usually carried by the late band member Ron "Pigpen" McKernan.  Cherokee Studios in Los Angeles was a regular haunt for the original Blues Brothers in the early days of the band. Belushi and Aykroyd became fixtures at the recording studio, while fellow Blues Brother Steve Cropper called Cherokee his producing home. Whenever they needed a bass player, they were joined by another Blues Brother, Donald "Duck" Dunn. During this time, Cropper, along with producing partner and Cherokee owner Bruce Robb, worked on a number of music projects with the two comedians/musicians, including Belushi's favorite band, Fear, and later Aykroyd's movie Dragnet.  The Blues Brothers Band continues to tour today, both with and without Aykroyd. The band features original members Cropper and Marini, along with vocalist Eddie Floyd. Aykroyd sometimes performs as Elwood, along with Belushi's younger brother Jim Belushi, who plays "Brother Zee" on stage. They are most frequently backed by The Sacred Hearts Band.

Question: James Buchanan Jr. was born in a log cabin in Cove Gap, Pennsylvania (now Buchanan's Birthplace State Park), in Franklin County, on April 23, 1791, to James Buchanan, Sr. (1761-1821), a businessman, merchant, and farmer, and Elizabeth Speer, an educated woman (1767-1833). His parents were both of Ulster Scottish descent, the father having emigrated from Milford, County Donegal, Ireland, in 1783. One of eleven siblings, Buchanan was the oldest child in the family to survive infancy.

In March 1860, the House created the Covode Committee to investigate the administration for evidence of offenses, some impeachable, such as bribery and extortion of representatives in exchange for their votes. The committee, with three Republicans and two Democrats, was accused by Buchanan's supporters of being nakedly partisan; they also charged its chairman, Republican Rep. John Covode, with acting on a personal grudge (since the president had vetoed a bill that was fashioned as a land grant for new agricultural colleges, but was designed to benefit Covode's railroad company). However, the Democratic committee members, as well as Democratic witnesses, were equally enthusiastic in their pursuit of Buchanan, and as pointed in their condemnations, as the Republicans.  The committee was unable to establish grounds for impeaching Buchanan; however, the majority report issued on June 17 exposed corruption and abuse of power among members of his cabinet, as well as allegations (if not impeachable evidence) from the Republican members of the Committee, that Buchanan had attempted to bribe members of Congress in connection with the Lecompton constitution. (The Democratic report, issued separately the same day, pointed out that evidence was scarce, but did not refute the allegations; one of the Democratic members, Rep. James Robinson, stated publicly that he agreed with the Republican report even though he did not sign it.)  Buchanan claimed to have "passed triumphantly through this ordeal" with complete vindication. Nonetheless, Republican operatives distributed thousands of copies of the Covode Committee report throughout the nation as campaign material in that year's presidential election.
