Well I'll tell you this IMO.
PF2 was live as far as the lead vocals. Shanias's voice was not as deep or sexy as it is on the song or Video. Backing vocals of course were recorded. Billy was off a little

MIFLAW was mostly live lead vocals with backing vocals recorded

Whose bed was the same. Lead vocals live, backing vocals recorded.

All in all a pretty darn good show. Can't wait to see the CMA's
