Input: Question: What position did Rebecca Hollweg's grandfather play? Passage 1:"My Father's Song" was released as the album's lead single in August 1975. The 7" record was released in the United States and Spain where the song was retitled "La Cancion de Mi Padre". The song was paired with B-side "By the Way", although in Spain the track was titled "Da Paso". The single enjoyed success on the United States Adult Contemporary chart, where it peaked at numbers 11. It also entered the similar chart in Canada, where it reached number 15. Nicky Siano, a disc jockey, began playing Streisand's version of "Shake Me, Wake Me (When It's Over)" at The Gallery nightclub in New York City in the fall of 1975; in a handwritten letter by Streisand for Siano, she wrote that the hype generated from playing her cover at the club prompted Columbia Records to release it as another single from Lazy Afternoon. It was distributed in 7" and 12" vinyl formats on November 12, 1975 featuring the B-side and album track "Widescreen". A British version of the single was also created and features the longer cut of the single instead of the album version. Streisand's cover was noted by writers for Billboard as an attempt for pop singers to begin "releasing disco records"; other singers like Andy Williams and Ethel Merman were also mentioned as individuals following the fad. Due to heavy airplay in dance clubs, it entered two of the dance charts compiled by Billboard; it peaked at number 14 on the Dance Club Songs chart and number 10 on the Disco Singles chart.

His murals are in the Charlotte Street Hotel and the Soho Hotel in central London.

Passage 3:The area around present-day Atsugi city has been inhabited for thousands of years. Archaeologists have found ceramic shards from the Jomon period at numerous locations in the area. By the Kamakura period, this area part of the Mori shoen, part of the holdings of Oe no Hiromoto. His descendants, the Mori clan later ruled Choshu domain. During the Kamakura period, the area was also known for its foundry industry for the production of bells for Buddhist temples. The area came under the control of the Ashikaga clan in the early Muromachi period and was later part of the territories of the Later Hojo clan from Odawara. With the start of the Edo period, the area was tenryo territory controlled directly by the Tokugawa shogunate, but administered through various hatamoto, as well as exclaves under the control of Odawara Domain, Sakura Domain, Mutsuura Domain, Ogino-Yamanaka Domain and Karasuyama Domain. After the Meiji Restoration, the area was consolidated into Aiko District of Kanagawa Prefecture by 1876. Atsugi town was created on April 1, 1889 through merger of several small hamlets. Atsugi was elevated to city status on February 1, 1955 through merger with neighboring Mutsuai Village, Koaiyu Village, Tamagawa Village and Minamimori Village. The city expanded on July 8, 1958 through merger with neighboring Echi Village, and with Aikawa Village from Naka District. On September 30, 1956, Ogino Village joined with Atsugi. In April 2000, Atsugi exceeded 200,000 in population and was proclaimed a special city with increased autonomy from the central government.
