Just to clarify something, I appreciate live music and live singing as much as the next person, I just couldn't get into what Sir Paul was putting out. I don't think it's a generational thing, either. If I like the song, I like the song. And though I liked the songs to a point, I just thought his voice wasn't as powerful to really push the songs. I'm sure that's because of age, more than anything else, but that's JMO of the performance last night.
And to slightly defend some of today's artists, some of them do sing live and are pretty good at it. Unfortunately, they're outnumbered by those who can't.
