Prodigal Son in the Key of F

Feeling footloose and frisky, a featherbrained fellow forced his fond father to fork over the farthings and flew to foreign fields and frittered his fortune, feasting fabulously with faint friends. Fleeced by his fellows in folly, and facing famine, he found himself a feed flinger in a filthy farmyard. Fairly famishing, he fain would have filled his frame with foraged food from fodder fragments.
"Fooey! My father's flunkies fare far finer, " the frazzled fugitive forlornly fumbled, frankly facing the facts. Frustrated by failure and filled with foreboding, he fled forthwith to his family. Falling at his father's feet, he forlornly fumbled, "Father, I've flunked and fruitlessly forfeited family favor."
The farsighted father, forestalling further flinching, frantically flagged the flunkies to fetch a fatling from the flock and fix a feast. The fugitive's fault-finding brother frowned on fickle forgiveness of former folderol. But the faithful father figured, "Filial fidelity is fine, but the fugitive is found! What forbids fervent festivity? Let flags be unfurled. Let fanfares flare." And the father's forgiveness formed the foundation for the former fugitive's future fortitude.
