But writing quite large in [Rosie] Hmmm. I read Marc's line as While skiing one day in Zermatt (which I think puts the correct stress in the place name), not While skiing one day in Zermatt. I agree you need a pretty strong (perhaps American?) accent to rhyme it with 'pot', though.
[irach] sorry to interrupt - but does your line scan - like really? Or is it just me that's having difficulty. I'm surprised - because you're usually spot-on in scansionland.
