Although "Morrison Hotel" contains no major hit singles, it features some of the band's most popular songs, including "Roadhouse Blues" and "Peace Frog", which would go on to become staples of classic rock radio. "Roadhouse Blues" took two days to record (November 4–5, 1969) with Paul Rothchild striving for perfection. Several takes from these sessions were included on the 2006 remastered album, with Morrison repeating the phrase "Money beats soul" over and over again. The sessions only took off on the second day, when distinguished blues guitarist Lonnie Mack (also signed to Elektra Records) joined in on bass and former Lovin' Spoonful bandleader John Sebastian (appearing under the pseudonym G. Puglese either due to the constraint of his Reprise Records recording contract) joined in on harmonica. Over the course of the session, keyboardist Ray Manzarek switched from his Wurlitzer electric piano to a tack piano previously used on the Beach Boys "Good Vibrations".
