WHAT A WONDERFUL FISH A SOLE IS
[As sung by Sid Fowler, recorded by Roy Palmer, in 1986, at the Nautical Club, Birmingham.]

What a wonderful fish a sole is!
What a wonderful fish are soles!
I'm partial to plaice when laid on a plate,
Or even made into rissoles.
What a wonderful fish a sole is!
Like salmon, they all swim in shoals.
But the best of all fish, when laid on a dish,
Are soles, are soles, are soles.

[I'm not sure, but I suspect he is omitting the final "s" in "soles." Maybe he is treating "sole" as a noun like "sheep," that can be either singular or plural. Who knows? Maybe he's right. The pun works equally well either way.]
