Great thanks. I assumed it was the original Hello vocal on there with some sort of voice effect. They should haved used a vocal from an alternate take, assuming that they are laying around somewhere.
The vocal for Hello, I Love You is the studio version. Regarding parts that were restored, there are too many to name. Just a few: the WTMO intro is longer. The original LMF vocal was restored. Many of Robby's original guitar parts throughout the performance were restored.
I'll have dig out my Hollywood Bowl CD and do some comparisons.
Did you pick up the dvd or bluray?
