I listened again to the recordings made by Manfred Mann, Emerson & Waldron, and The Country Gentlemen, and I see no reason to alter what I wrote on 25 Oct 11.

"I'll fill a straight of girls" might not mean anything to those who don't know poker, but it's a striking metaphor, and I think it'd be a shame to lose it. "I see a stream of girls" is pretty weak by comparison.
