"Three Gershwins..." & Other Tripartite Situs Limn'd as Lim'ricks

A Shwin / Shwin / Lose Situation 

Three Gershwins seem show business pros.
There be George, brother Ira and Rose.
George's tunes are the best.
Ira's words pass the test.
Yet all shows of Ms. Rose quickly close.

A Wright / Wright / Wrong Situation  

Three Wrights seem a laudable trio.
There be Orville and Wilbur and Leo.
Orville's printing press...? Nifty.
"Burr"'s bicycles...? Thrifty.
Yet, Dio! Poor Leo lacks brio!

A Grant / Grant / Keep Situation 

Of Grants we observe more than two.
There's Ulysses. There's Gogi. There's Hugh.
Uly's POTUS -- two terms.
Gogi's hairdos are perms.
As to Hugh, I've no clue. Nor have you.

"If each holiday song, gotten jotted down wrong..." Ymas Story or There's No Place Like an Alternate 'Yule'niverse for the Holidays

If each holiday song, gotten jotted down wrong,
reappeared, but sung weird and inchoate,
would've stuff taking place showed a different face?
Would the world have unfurled as we know it?

If (say) Clement Clarke Moore had penned "Fortnights Before..." --
this in lieu of the lyrics we love,
then would issues of race now but rarely take place?
Would each push need to come to a shove?

And if Bach's "Hallelujah" were sung "If I knew ya
were coming I'd bake ya a cake,"
would've Adam's mate Eve from God's garden took leave,
scarffed a pear and then married the Snake?

If a true lover sings. "...five aluminum rings..."
in his air about pear trees and partridges,
would've JFK's 'cade proved a less grim parade?
Would Lee Harvey have run short of cartridges?

If those Magi guys were from the Occident, myrrh,
gold and frankincense might have, instead,
been a Myrtle Beach condo, one Golden Fernando
and Frankenstein's second-best bed. 

Had he* dashed through the snow in a multi-horse No-
va instead of a single-horse sleigh,
would they've figured a way -- that proverbial "they" --
to prefabricate Rome in one day?     
     * James Lord Pierpont, composer of "Jingle Bells."

And had Frosty the Snowman proved less tele-showman
and more ecological hero,
would the globe have stopped warming, stopped tropical storming?
Would rumors of war approach zero?
