The event was in action comics weekly and occurred after the Malvolio encounter that changed hal's ring.
John Stewart as I recall was reactivated by Hal in GL quarterly and was off earth at the time
Clark was chosen by Abin but after seeing he was Kryptonian disqualified him as regulations state a native to the sector must be chosen. Clark gave first aid and abin wiped his memory and sent him back.
Than came the choice of Hal or Guy but Hal was closer.
Hal is shot and dying his ring scanned and pulled several candidates including Clark Kent, Guy who was already a GL and not present at Sinestro being executed and blowing up the CPB, Deadman, Nightwing and some civilians were chosen. All but Clark and Deadman were time frozen and Hal was trying to choose while Clark and Deadman argued the pros and cons of living and dying.
Then a pre-recorded message of abin came from the ring, which could not have happened as this was Malvolio's ring. It urged Hal to remember his will power, that abin died from lack of will and that the candidates had lesser will then Hal.
Hal revives himself and sends the candidates back and defeats the corrupt soldiers that shot him.
After this the comic becomes action comics again for Superman only, GL vol three is launched, Hal would have white hair at the launch and would be slowly poisoned by Parralax.
I have often suspected this incident was one of parallax's attacks on Hal to slowly poisoned bis mind
And then in Emperor Joker, DC showed to us that Supes had greater willpower than with Bruce or Hal!
