I'm not sure what the technical name for singing two different songs together, but I recall several years ago hearing a duet with one person singing "A Spanish Cavalier" and the other singing "Soloman Levi." Anyone know the words to that one???
All I can remember is:
My name is Soloman Levi
And my store's on Salem Street
That's where you buy your coats and hats
And everything else that's neat.
Second handed (?????)
And (????) so fine
For every young lad that smiles at me
