Weird, I always thought everyone disliked Harvest. I hate that song, it's boring like hell, the vocal lines are uninspired and the songs sounds like a wannabe commercial song (structure etc..). 99% of the times I put on BWP I skip that song.
Benighted rules. I think someone should play it on a piano, I once replaced in GP4 all the guitars with pianos, and it sounded really great. But Never let go is indeed even better.
