Ok, so I'm looking at IBDB, and it has 4 people covering Hugh Jackman. Two standbys (Kevin Spirtas and Mark Halling) and two understudies (Brad Anderson and John Hill).
I have a playbill from April, it doesn't list either standby, and Anderson (who replaced Hill in his roles) is the only one listed.
My question is, did IBDB just mess up, or did they really have 4 people covering him?
