The vocalist/bassist is the same as on Aqua (John Payne). The drummer and the two guitarists were members of Asia with Payne and Geoff Downes in the early 2000s, before Downes broke up the group to reunite with the original lineup. They (drummer and guitarists) stuck with Payne in his spin-off bands, Asia featuring John Payne and GPS. The keyboardist (Erik Norlander, from Rocket Scientists and Lana Lane) replaced Downes in AfJP. Payne and Norlander decided to discontinue the use of the name 'Asia' after John Wetton's death last year, so now they're calling themselves 'Dukes of the Orient'.
Yeah, keeping track of Asia's lineups is a little complicated. Given that the band is a direct descendant of Yes and King Crimson, this is hardly surprising.
