... Yes Ewan McColl did wear a kilt, probably a middle class kilt, it's a little known fact that one of the earliest songs he wrote was the famous 'Donald where's yer Troosers?'
Printed below is the verse that Andy Stewart never sang on the White Heather Club...

'On a walking holiday in Wales,
the lassies all gave shouts and wails,
when I walk through the heather well I leave three trails
when I havenae on ma troosers!'

Let the wind blow high etc...
