Bristol Bears coach Pat Lam has added a further four test internationals to his Barbarians squad to face England on June 2.
Former All Blacks Charles Piutau and Liam Messam, along with powerful Fijian No 8 Viliame Mata and Argentinean loose forward Facundo Isa, will join Steven Luatua, Malakai Fekitoa and John Afoa for the clash at Twickenham.
Between them Piutau, Luatua, Messam, Fekitoa and Afoa share 135 tests for the All Blacks.
In the same fixture last year, Lam led the Barbarians to a stunning 63-45 victory over England.
Welsh halfback Rhys Webb and Fijian wing Filipo Nakosi are other already-announced squad members.
Lam hopes the Baabaas will produce a performance to honour the memory of long-standing club president Micky Steeele-Bodger, who passed away aged 93 last week.
"Everyone involved in rugby was sad to hear about Micky's passing," Lam said. "He was such a great character, gave so much to the game for so long, and held strong beliefs about the way it should be played on and off the field.
"The players and management will honour his memory as much as we can in the competitive and exciting way we try to play the game, and in the friendships that will be established by a unique group of players."
