Problem: Premiata Forneria Marconi (PFM) (translation: Award-winning Marconi Bakery) is an Italian progressive rock band. PFM were the first Italian group to have success abroad, entering both the British and American charts. Between 1973 and 1977 they released five albums with English lyrics. They also had several successful European and American tours, playing at the popular Reading Festival in England and on a very popular national television program in the United States.

The lack of a strong lead vocalist had always been considered PFM's biggest liability so, for this reason, they enrolled Bernardo Lanzetti, who was previously with the group Acqua Fragile. While a college student, Lanzetti had lived in Austin, Texas for a few years. But most importantly he had a powerful and distinctive voice and could speak fluent English. The first release by the six-piece band was Chocolate Kings in 1975. Featuring a harder rock sound, it had modest success at home but was their least popular album in Italy so far. The same album was released with different cover art by Manticore in the UK and by Asylum Records in the US. The controversial US/UK cover showed a chocolate bar in a partially peeled Stars and Stripes wrapper on the front, along with the crumpled and discarded wrapper on the back. PFM appeared on the BBC television show The Old Grey Whistle Test in 1976 performing the title track to the album. The album reached the UK top 20 but was less successful internationally. Mauro Pagani left the group following Chocolate Kings to pursue a solo career. Lanzetti also appeared on Jet Lag (1977), an album highly influenced by the Jazz-fusion movement, which was recorded in Los Angeles. This was their last album with English lyrics and the last album released in the U.S., also on Asylum. Violinist Gregory Bloch, previously with the group It's a Beautiful Day, replaced Mauro Pagani and helped the band acquire notoriety in the US before leaving to join the Saturday Night Live Band in 1979. For Passpartu (1978) PFM added two new percussion players and shifted stylistic direction once again. The album contains seven songs in Italian and one instrumental, characterized by an international pop music style; an early example of what today is known as 'Worldbeat'. The album contains mostly acoustic guitar and draws from Italian folk and Latin music as well as Jazz-Pop styles, somewhat like Steely Dan. This was the last album to feature Lanzetti, who then left to pursue a solo career.

Question:
David Gaub McCullough (; born July 7, 1933) is an American author, narrator, historian, and lecturer. He is a two-time winner of the Pulitzer Prize and the National Book Award and a recipient of the Presidential Medal of Freedom, the United States' highest civilian award. Born and raised in Pittsburgh, McCullough earned a degree in English literature from Yale University.
After the success of The Johnstown Flood, two new publishers offered him contracts, one to write about the Great Chicago Fire and another about the San Francisco earthquake. Simon & Schuster, publisher of his first book, also offered McCullough a contract to write a second book. Trying not to become "Bad News McCullough", he decided to write about a subject showing "people were not always foolish and inept or irresponsible." He remembered the words of his Yale teacher: "[Thornton] Wilder said he got the idea for a book or a play when he wanted to learn about something. Then, he'd check to see if anybody had already done it, and if they hadn't, he'd do it." McCullough decided to write a history of the Brooklyn Bridge, which he had walked across many times. To me history ought to be a source of pleasure. It isn't just part of our civic responsibility. To me it's an enlargement of the experience of being alive, just the way literature or art or music is. - David McCullough He also proposed, from a suggestion by his editor, a work about the Panama Canal; both were accepted by the publisher. Critics hailed The Great Bridge (1972) as "the definitive book on the event." Five years later, The Path Between the Seas: The Creation of the Panama Canal was released, gaining McCullough widespread recognition. The book won the National Book Award in History, the Samuel Eliot Morison Award, the Francis Parkman Prize, and the Cornelius Ryan Award. Later in 1977, McCullough travelled to the White House to advise Jimmy Carter and the United States Senate on the Torrijos-Carter Treaties, which would give Panama control of the Canal. Carter later said that the treaties, which were agreed upon to hand over ownership of the Canal to Panama, would not have passed had it not been for the book.
