Cover art for Begging You lyrics by Stone Roses, The

For me this song was about doing some lines - "dust", "ready to blow", "his stings all gone Now he's begging you, begging you" is all about coke and wanting to do more. "Make all the dust that you can."

Then, there is a bit of imagery about Jesus with the sky dividing and being gone but still with you...

But mostly the frantic intense nature of the song induces the speed feeling of doing some dust.

I have no idea what the fly on the coachwheel is about.

So, given their histories I'd say Brown contributed the Jesus imagery and Squire had the dust parts.
