Question: Was the coach that Culverhouse hired younger than the person he replaced? Passage:Former Atlanta Falcons coach Leeman Bennett was named by owner Hugh Culverhouse as the replacement for retired head coach John McKay. Other candidates interviewed included Buccaneer defensive coordinator Wayne Fontes, Seattle Seahawks defensive coordinator Tom Catlin, former Michigan Panthers head coach Jim Stanley, former New England Patriots head coach Ron Meyer, Washington Redskins quarterback coach Jerry Rhome, former Pittsburgh Steelers defensive coordinator Bud Carson, and former Florida Gators coach Charley Pell. Bennett was an unexpected choice, as Fontes had long been considered to be the leading candidate and had the near-unanimous support of the players and existing staff. Culverhouse almost gave Fontes the job without conducting an interview process, before having second thoughts and soliciting recommendations from McKay, Tex Schramm, and Dan Rooney. Described as "heartbroken", Fontes learned while attending a scouting combine in Arizona that he had been passed over for the job. Bennett indicated that nobody who had been a candidate for the head coaching job would be hired as an assistant, ending speculation that he might retain Fontes or bring in his former assistant Jim Stanley. Fontes eventually accepted the defensive coordinator position with the Detroit Lions.

Question: How long before "Promise This" was released was the city it was recorded in established? Passage:"Promise This" is an up-tempo dance-pop song written by American songwriter Priscilla Hamilton, British music producer Wayne Wilkins, who was responsible for Cole's debut single "Fight for This Love", and Christopher Jackson. It is written in the music key of C minor with a time signature in common time and a tempo of 151beats per minute. Cole's vocal range spans from G to E. The basic chord progression of the song is Cm, Cm, Cm, Cm, E, B, F, Cm, E, B and F. The song sees Cole singing some of the lyrics in French, referencing the children's song "Alouette". It was recorded in Santa Monica, California, and "finds her contemplating mortality with a cheerful morbidity, asking for prayers over a brutal march beat." Tabloids suggested that the lyrics were based upon her divorce from footballer Ashley Cole, and how her dancer friend Derek Hough nursed her to health while she was suffering from malaria. The Daily Star had also noted Cole's apparent affection in the song by her use of the French word alouette, meaning "skylark".
