Lione who also handled lead vocals for KAMELOT on the band's North American trek stated in an interview that he would "would love" to join KAMELOT permanently. He said, "The KAMELOT songs are great, I really like the style and Khan is probably one of the few singers that I like. So, of course, I would consider that!!! But first let's do the North American [tour]. Then if they will ask me, I'll be more than happy to join the band permanently." He added, "Since the first time we met and played together, we had a very good feeling. Everything was easy and natural like we knew each other for years and everybody who saw the band in South America or Europe said we did great shows. I'm happy for the guys and the fans, so let's see what the future will bring for us. Never say never." The remaining members of KAMELOT have already begun searching for a permanent replacement, with KAMELOT founder/guitarist Thomas Youngblood stating in a recent interview, "I have a few guys in mind. And as you can imagine, it is a very important decision. There are some amazing singers that have already contacted us on this but we will take our time to find the right person."
