Paul still matters to me and thats all that really matters.
I don't buy everything he makes these days although i bought Chaos and i was impressed by that album which was full of good songs .
It's up their with Ram ,Band on the Run and London Town as my personal faves .
And im looking forward to Memory Almost Full as i think Paul is in a good creative patch at the moment and if it's anything like Chaos i will be well pleased.
As for His relevance today who knows . He's a Beatle and we only have the two left and lovely old Ringo an't gunna knock out an earth sattering album
And this could well be his last album ,the title is a big clue, maybe he will do McCartney 3 , but we are not going to get much more from him i feel in terms of rock albums.
And i agree the money is in the tours these days and most of the older rockers know that.
Im a big fan of the late Marc Bolan and T.rex and i can tell you i would have given anything for him to produce a few more good bad indifferent albums.
So the fact that Paul is still making them 37 years after The Beatles split is great .
It matters to him , so it matters to me
