I admire McCartney hugely,always have since I first heard the Beatles as a kid, right the way through to his Glastonbury set last summer. Yeah his voice is about done now but he’s 80, Sinatra was the same but he was still great to watch. Some of his Wings stuff was good, some was a bit twee, some was crap but he has adapted over the years and been successful which I believe is to be admired. My all time favourite artists are the ones who changed as the years went along and remained relevant. They didn’t go down the route some wanted them too, they did what they wanted and said ” well this is me now, if you like it buy it, if you don’t fine, I’m not changing”. I’ve always had a huge range of different musicians I like and admire as a lot of other people do but the all time greats,IMO, just stand out head and shoulders above most because of their ability to change, adapt and be successful, that’s real talent for me.
