Input: Consider Input: Question: In what current day city would the Church of the Holy Apostles be located in? Passage:The facts regarding Constantine's life are confused and subject to conjecture. It is known that at the time of Emperor Leo VI the Wise (r. 886–912), he restored a monastery near the Church of the Holy Apostles, which is nowadays identified with the Fenari Isa Mosque on account of a partial inscription commemorating its dedication to the Theotokos. The date of the inauguration is traditionally placed in 907/908. Constantine Lips also participated in the failed coup of the prominent general Constantine Doukas against the infant Constantine VII Porphyrogennetos (r. 913–959) in July 913, after the death of Leo's brother and successor Alexander (r. 912–913). In its wake, several nobles who had been or were suspected of being involved in the coup were executed, while others fled the city, amongst them Constantine Lips. On August 20, 917, he fell at the Battle of Acheloos, fighting against the Bulgarian forces under Simeon I.

Input: Consider Input: Question: Is the person who cited Yoakam as his favorite country singer still alive today? Passage:Johnny Cash once cited Yoakam as his favorite country singer. Chris Isaak called him as good a songwriter as ever put a pen to paper. Time dubbed him "A Renaissance Man" and Vanity Fair declared that "Yoakam strides the divide between rock's lust and country's lament." Along with his bluegrass and honky-tonk roots, he has written or covered many Elvis Presley-style rockabilly songs, including his covers of Queen's "Crazy Little Thing Called Love" in 1999 and Presley's "Suspicious Minds" in 1992. He recorded a cover of The Clash's "Train in Vain" in 1997, a cover of the Grateful Dead song "Truckin'", as well as Cheap Trick's "I Want You to Want Me". He has never been associated only with country music; on many early tours, he played with hardcore punk bands like Hüsker Dü, and played many shows around Los Angeles with roots/punk/rock & roll acts. His middle-period-to-later records saw him branching out to different styles, covering rock & roll, punk, 1960's, blues-based "boogie" like ZZ Top, and writing more adventurous songs like "A Thousand Miles From Nowhere". In 2003, he provided background vocals on Warren Zevon's last album The Wind.
