I imagine Buzz's buddy had to amplify his Gilled because he was Herring-impaired !
I had an old Chum years ago who had a Gilled; sounded pretty Crappie, but then, he had no musical ambitions.... he only played for the Halibut.
He Floundered around on that thing, and eventually attracted the attention of the little red-haired Ho next door, Anne Chovie, who he affectionately christened the Orange Roughy. Unfortunately, the relationship fell apart when he made a clumsy attempt to Grouper. She Skated off pretty smartly, and last I heard, she had married a bloke named John Dory.
Undeterred and unphased, my Chum cocked a Snook and practised harder on his Gilled. He eventually formed a band named Rockfish, who briefly challenged Fleetwood Mackerel on the English charts. They had a #12 hit with a re-make of the Beatles "Here Comes the Sunfish". Last I heard of them, they were doing Sole covers at the stunned Mullet.
