Perhaps, but it just seems so icky. If it was a joke, perhaps he needs to work on his delivery! I love a good joke. But this fell flat with me, even watching it again now. Or else he might want to just stick to the music part of the entertainment business and stay in his lane which is playing the guitar (ie, not comedy!).
Maybe it's just lost on me...
It's like how he will inadvertently take credit for the ICTYW solo if someone compliments him on a great solo by not correcting them. You have to literally pin him down and ask who actually recorded it to get him to say it was Glenn's solo. But if you just assume it was Don, and praise him for it, he's all in. Of course his retort might be "well, I assumed they meant how well I executed it live...". I find Don's narcissism while calling Glenn and DH narcissists very ugly and not at all appropriate for a man in his 70s. Be humble!
