Question: Question: Who were the other members of the band that Patrick and Bill both left? 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: Question: How many Boy Wonder's have there been? Passage:Besides the aforementioned death of Stephanie Brown, many other side effects came about from this event. The biggest of these included Black Mask becoming the single crime boss in Gotham, something that would remain until his death at the hands of Catwoman. Another would be Commissioner Akins effectively making all vigilantes criminals, a move that would stay in place for over a year until the return of Commissioner Gordon to the Gotham City Police Department. The more controversial effect, not seen until the follow-up story War Crimes, was turning Doctor Leslie Thompkins against Batman, when she allows Stephanie Brown to die from her wounds as Batman's "punishment" for including children in his war on crime. Jason Todd, a former Boy Wonder, confirmed to be alive on  as a violent vigilante the Red Hood who waged a one-man war against Black Mask and successfully crippling his criminal operation in the city before seeking revenge towards Batman and the Joker. Finally, the citizens of Gotham City no longer consider Batman to be an urban legend (which has been in place since Zero Hour), as he was caught on camera trying to save the life of a wounded student at the end of Act One. Additionally, Barbara Gordon lost the clock tower that served as her home and headquarters and left Gotham City, eventually moving to Metropolis. She would later re-establish her ties to Batman.

Question: Question: Which music did Hand Williams, Jr. release right before his work on Waylon and Company? Passage:Jennings had recorded several duet albums in the past, including three in five years with Willie Nelson and one with his wife Jessi Colter in 1982, but Waylon and Company was his first album of duets with a host of guest artists. The album is best remembered for "The Conversation," a #4 hit with Hank Williams, Jr. that addresses the legacy of Hank Williams (the pair also shot a popular music video for the song). Waylon and Hank, Jr. also join an ailing Ernest Tubb on the defiant "Leave Them Boys Alone." Emmylou Harris, Jerry Reed, Mel Tillis, Jessi Colter, and actor James Garner also make appearances, and Jennings sings one song with Tony Joe White. Bob McDill wrote the lone Jennings solo track, "I May Be Used (But I Ain't Used Up)," which peaked at #15. The album contains the #1 hit single "Just to Satisfy You," a duet with Nelson which had actually been released in Black on Black LP two years earlier. The album peaked at #12 on the Billboard country albums chart. AllMusic deems the album "Fun for what it is."
