Glen Campbell brought his Goodbye Tour to the Irvine Auditorium at the University of Pennsylvania on Thursday night, in support of his powerful new album Ghost on the Canvas.

Campbell's been the subject of much media attention since revealing in June that he's been diagnosed with Alzheimer's disease, and part of the time he was up on stage at the not-sold-out 1200 capacity room Campbell was being filmed by a Fox News crew for a documentary about Alzheimer's.

The 75 year old guitarist – whose picking skills are undiminished – was supported on his farewell tour by a six piece band, featuring several of his own children, and he mixed in his big hits from the 1960s and 1970s like "By The Time I Get To Phoenix," "Wichita Lineman" and "Southern Nights" with a cover of Tom Petty's "Walls" and a number of songs from his new album written for him by the likes of Paul Westerberg and Teddy Thompson.

It was a uneasy evening, stretching just over an hour, with the legendary session musician clearly enjoying himself on stage and sometimes showing surprising vocal range, but also appearing disoriented and at one point, having to ask his longtime keyboard player T.J. Kuenster to remind him how old he was.

A full review is coming on Friday.
