Not really, remember back in 2005 when John Mayer was playing with Herbie Hancock? Pollstar (and some other sources, I think Jambase) had him listed individually. It happens from time to time.
remember when no one believed it was that john mayer. people were saying, no that's some other guy because it said john mayer (jazz guitarist) or something like that. for that reason i didn't even think about him being there and i missed that set.

AC is promoting Neil in Knoxville less than 3 weeks before Bonnaroo. We had sources confirm him and then go silent after the lineup. There is still room at the top of the lineup for a Neil solo acoustic pre-headlining set. You do the math.
