sinister tracks, like 'Lord of the Thighs', came from the seedy area where we recorded the album. 'Lord of the Thighs' was about a pimp and the wildlife out on the street." Tyler plays the piano on the track, the opening beat of which is similar to the one Kramer would play a year later in "Walk This Way". He stated that the title was a pun on the famous William Golding novel Lord of the Flies, and "the critics hated us for this. We weren't supposed to be smart enough to use literary references." One of the most well-known tracks is a cover of "Train Kept A-Rollin'", made popular by one of Aerosmith's favorite bands, the Yardbirds. According to Douglas, the crowd noise at the end of the track was taken from a "wild track" from The Concert for Bangladesh, which he had worked on. The single version omits the echo and crowd noise. Notable for its start/stop groove, the song became a core part of the band's live set for a time, and still occasionally ended concerts late in their career. In 1997, drummer Joey Kramer explained to Alan Di Perna of Guitar World that its unique rhythmic feel originated "probably just from jamming on it at soundcheck and experimenting with putting a James Brown kind of beat behind it. I played with a lot of R&B-type groups before joining Aerosmith." In the same interview, Perry stated that "Train" was the one song "we all had in common when we came together." The closing "Pandora's Box" was originally written by Kramer, who recalled in 1997: "The summer before, we'd rented a farmhouse in East Thetford, Vermont, while we were rehearsing in New Hampshire, and that's where I wrote the melody of 'Pandora's Box.' Steven wrote the lines about women's liberation, a big new issue in those times." According to Douglas, the clarinet at the start of the track is a union engineer playing "I'm in the Mood for Love". In 2014 Perry reflected, "We all put in endless hours, fueled by whatever substances were available... I knew the album, in spite of a few bright spots, still didn't capture the power of the band. We were better than the record we were making. And yet I didn't know how to get there. I didn't know how to get from good to great." "On the second album," Tyler noted,
