Question: How many albums total did the Beatles record in Hamburg? Passage:Ain't She Sweet was an American album featuring four tracks recorded in Hamburg in 1961 by The Beatles featuring Tony Sheridan (except for the title song with vocal by John Lennon) and cover versions of Beatles and British Invasion-era songs recorded by the Swallows. As Atlantic Records only had rights to four Sheridan/Beatle recordings recorded by Polydor Records, they filled the rest of the album with Beatle and British Invasion cover songs. When this material was released by Atco Records, there were mono (catalogue number 33-169) and stereo (SD 33-169) editions. Atco also added additional drum overdubs to the four Sheridan cuts on top of the original drum tracks. American drummer Bernard Purdie claims to have performed overdubs of unspecified Beatles records, which would most likely have been for Ain't She Sweet, but this has never been officially confirmed.

Question: In what countries are the headquarters of the churches that venerate Mari as a saint? Passage:Saint Mari, also known as Mares and originally named Palut, is a saint of the Church of the East. He was converted by Thaddeus of Edessa (a.k.a. Addai) and is said to have had Mar Aggai as his spiritual director. He is believed to have done missionary work around Nineveh, Nisibis, and along the Euphrates, and is said to have been one of the great apostles to Syria and Persia. He was buried in Dair-Kuni. His feast day is 5 August in the Christian calendar. He and Thaddeus are credited with the Liturgy of Addai and Mari. Despite the fact that there is little, if any, concrete information on Mari, he is still venerated as a saint by the Assyrian Church of the East, the Chaldean Catholic Church, the Roman Catholic Church, and the Syro-Malabar Catholic Church. He is distinct from St Mari of the seventy disciples with whom the Apocryphal Acts of Mar Mari are connected.
