Paul Weller and... the crowd..
The Jam have been one of my favorite bands - if not my outright favorite - for decades. The songs Weller penned over that period have left a lasting impression. It is great to see a current day crowd lock in step with him on a tune that's 40 years old. That says something.
But since this about duets, which I'll take the liberty of defining loosely, I think of the tunes he went back and forth on with Bruce Foxton supporting each other vocally - tunes like In the Street Today and Smithers-Jones, for example. And while I generally don't care for his Style Council material, Speak Like A Child may loosely qualify. It stands out to my ears as the best tune of his Style Council run.
