Robert Marien had an alternate in the 10th anniversary Broadway cast (Ivan Rutherford), and I think John Owen-Jones was Stig Rossen's alternate in London for a while.
I first heard an alternate Valjean was a possibility for this tour about a year ago, owing to its relatively short stops. Funny how they quietly just released that info.
Adam is correct, and this was also true for the third national tour (and, I assume, the previous two as well).
