Are there really enough songs about rainbows to actually warrant someone writing a song asking why there are so many songs about rainbows? 🤔

You really need to get out more! 🤷‍♀️

Billion...

10^12 = British billion (because "bi" denotes 2 so signifies million^2, i.e., squared);

10^9 in America whose Founding Fathers banned e-t-y-m-o-l-o-g-y!

Are there really even only some thousands of millions of songs known?

Still, with so few mentioning rainbows, and none referring to such songs themselves; now's your chance, FordPrefect, for fame and fortune in what used to be called the 'Hit Parade'. :-)
