It took until 2018 to confirm that "Suitor" existed on a tape other than this known Rainbow live performance recording. While preparing material for his 2019 book, "Backstage Pass," Paul Stanley unearthed an acoustic reel of Wicked Lester (dated Aug. 7, 1971), presumably of them running through their then catalog of songs. By the time of KISS Kruise VIII, Paul was unable to confirm whether the tape had been transferred or if there were any plans for the material. Paul has stated that Wicked Lester never properly recorded the song.
