Question: Are both of the band members who put out the album "Flags" still alive? Passage:Flags is a 1985 album by the duo Moraz-Bruford. Unlike their prior effort Music for Piano and Drums, which featured only an acoustic drum kit and grand piano, this recording expanded their musical palette by including a Kurzweil 250 synthesizer and electronic percussion. Keyboardist Patrick Moraz and drummer Bill Bruford had both previously been members of the progressive rock band Yes (though at different points in time) and also appeared together on Chris Squire's first solo album Fish Out of Water. During the recording of this album, Moraz was a member of The Moody Blues, while Bruford's band King Crimson had just begun a hiatus that would last for ten years. Flags features ten instrumental works, including a drum solo based on Max Roach's "The Drum Also Waltzes".

Question: How many times has the artist whose version of "Canadian Sunset" reached #1 in 1956 had a #1 single? Passage:Gimbel was born on November 16, 1927 in Brooklyn, New York, the son of Lottie (Nass) and businessman Morris Gimbel. His parents were Austrian Jewish immigrants. Gimbel was self-taught in music and following initial employment with music publisher David Blum, progressed to become a contract songwriter with Edwin H. Morris Music.
