			A beautiful little skit! They don't make 'em like that anymore.
 
Only the words 'eating', Easter', 'egg', and 'evening' started with the letter 'E"! Everything else just emphasized the long 'e' sound within the words. 
So, it was and it wasn't a skit about the letter 'E'.
		
		
	 
The earliest episodes showed at least two other cartoon-songs with the key vowel in other parts of a word, not just the beginning:
 
"The train to Spain was late today:  an ape pulled the brakes...And made it get awaaaaay!"
 
"O-O-O-O-O-O-O-Oooo.. 
Grow and go 
Roll over the road 
Where the goat explodes all the Os 
And the crow flies low 
Past the croaking toad 
And the boat floats over the ocean..."
 
[Thanks to Tiny Dancer for the lyrics to "The O Song", by the way...]
 
If a different approach helps children learn the way letters and sounds relate to each other, what's wrong with using it?  The older vowel cartoons showed the sound being used in the middle of some words because a vowel is more likely to appear in the middle of a word, not at the beginning.  
 
Besides, Sesame Street has treated one other letter differently before:  I've watched older clips about words that 
ended with X instead of the usual "X-ray/xylophone/marks the spot" fare.  (The most recent one I remember dates to the mid-90s, when the show still had two letters of the day:  A Muppet fox visits the street and challenges Telly to think of three words that end with X.  The other two clues are right under his nose, since the animal's playing a sax and wearing a tux...I don't think most kids would be familiar with that last word, though.)
