Just had an argument in the pub with a mate about this and i have to admit he did have a point (although he was pissing in the wind if he thought i'd admit it!).
He said Happy Mondays started Madchester and the likes of the Stone Roses, Northside, Charlatans etc all got dragged along for the ride. Now i agree with him upto that point, but then he pointed out that someone else was really responsible - VINCE FUCKING CLARKE!
Vince Clarke remixed "Wrote For Luck" into "W.F.L." which was the blueprint for everything the Mondays did after that, and without that remix there probably wouldn't have been the Oakenfold mix of Hallelujah, which led to Oakey producing "Pills,Thrills & Bellyache!" which was undoubtedly THE madchester album.
So Clarke of the (by 1989) washed up uncool Erasure accidently made what has arguably become Happy Mondays best 6 minutes and changed music forever.
I told him he was talking bollocks. But he might just be right...
