Well, Mike, poetic licence is one thing, bad rhyming when you dont know any better, is another.
Of course you can say legEND if you want - you can say
sushi rhymes with
cheeseburger if you want - but why settle for less than best? LEGend or LEGund, either way it isnt stressed on the second syllable and if you try to force it that way, it just wont sound right.
Its the kind of thing thats done a lot in song lyrics. With a melody you can get away with it, because you hear it sung and get the idea of how its supposed to go. But the written word read unaided, needs to be like English as its spoken, or youll lose the reader. (I think, anyway)
Your lines are good, MCC, and
the end rhyme is fine, considering the options. I hope I havent put you off. Theres just something about Mike that brings out the bossy britches in me!
