Question: Which Bristol City F.C. manager that Goodfellow played for had a longer tenure with the club? Passage:He made only a handful of appearances at the Britannia Stadium in 200304, though he earned a 50,000 move to Bristol City in the January transfer window. He played in the play-off final defeat to Brighton & Hove Albion, replacing defender Tony Butler on 88 minutes as manager Danny Wilson made a late attempt to save the game. He did not feature heavily at Ashton Gate and instead was loaned out to Port Vale in October 2004. The next month Swansea City manager Kenny Jackett was on the lookout for a quality winger, Goodfellow meanwhile was prepared to go out on loan to the League Two club. Jackett managed to persuade City to allow Goodfellow to join the "Swans" on loan. He impressed at the Welsh club and his loan spell was extended the following month. However, he was quickly recalled to Ashton Gate after a spate of injuries at the Bristol club. Soon after Swansea attempted to buy Goodfellow off City, however, City manager Brian Tinnion informed Goodfellow he still had a future at the club. Tinnion was expecting at least what they paid Stoke for him and Swansea were unable to comply. In March 2005 he joined Colchester United on loan until the end of the season and scored once against Peterborough United.

Question: How old is the city where Scared of Beautiful was made? Passage:"Scared of Beautiful" was written by Odd Future collective member Frank Ocean along with producer Warryn Campbell, and Chameleon Records head Breyon Prescott. Jaycen Joshua mixed the track, while Trehy Harris assisted in the audio engineering of it; both tasks were executed at the Larrabee Sound Studios, in North Hollywood, California. In early March 2012, Norwood made known that Ocean would contribute to her then upcoming sixth studio album, Two Eleven. He previously wrote the songs "1st & Love" and "Locket (Locked in Love)" for her 2008 album Human, a process which resulted in a close friendship between the singers. Though Ocean didn't write "Scared of Beautiful" specifically for her, Norwood stated that she was owning it now: "It's on my album, I got a claim... 'Frank Ocean, you wrote that song for me, you just didn't know it'," she joked. Ocean's demo of the track was leaked in late 2011. Crafted by Midi Mafia members Waynne Nugent and Kevin Risto along with songwriters Tim Stewart and Lamont Neuble, it features a significantly different, guitar-driven instrumentalization. Campbell, unaware of Ocean's version, produced his own variation of "Scared of Beautiful" with help from Prescott along Norwood's pre-recorded vocals only.
