Another wee correction as from Hogg's Jacobite Relics " ... and then he ga'e his bags a wheeze ..."
The chorus was notated as to be sung after
" .. And played anither key" chorus
"Wi muckle mirth and glee" chorus
"Sae sweet, sae bonnilie" chorus
"That nicht at Amulrie" chorus

There is no mention of a final chorus (after "the piper o 'Dundee) but I suspect it would have been sung.
