Not really. In the early 2000s, before Quarry was recorded, a number of new songs were previewed. It was clear that two of these songs (Irish Blood and, in particular, First of the Gang) were much better than the others. They hadn't been 'produced' by anyone at that point.Nah, he was the right producer. The success of the album proves that.
When the album finally came out, these two songs were still easily the best, but not really much better or worse than their live previews from a few years earlier.
Producers can affect things a little but not that much. If they're given great songs, it'll be a great album - if they're given mediocre songs, it'll be a mediocre album.
This song (How can anybody know) is pretty awful - First of the Gang on the other hand is brilliant. They were both produced by Finn. The difference is that one is a great song and one's a bit rubbish.
