Song above (Jan 2011) updated.
I plan to use this at this year's Worldcon in Helsinki. Reference to "Folkies" will become "Filkers". otherwise unchanged.

Second verse added for the occasion. (it always needed one!)

Folkies sing at twilight,
When the lights are low.
And the youngsters' I-Pads
Cast a gentle glow.
Oldsters 'twit' the youngsters' goldfish memories.
Saying "Back in our day, we'd none of these,
We'd none of these"

Back in those dear dead days of good recall.
We never needed Aides memoire at all.
We all could stand and sing a lengthy song
So confident the words were never wrong.
Sing one more song, and sip another sup.
(There were no songbooks there to trip . us . up!)

Folkies sing at twilight,
When the lights are low.
And the youngsters' I-Pads
Cast a gentle glow.
Oldsters 'twit' the youngsters' goldfish memories.
Saying "Back in our day, we'd none of these,
We'd none of these"

Now after years there dawns a better time.
And singers have revised the paradigm.
Singing from books is strictly "for the birds"
So, take that leap and learn those folking words!
You'll feel the glow of kudos when you do,
And yet the age old chorus still comes through:

Folkies sing at twilight,
When the lights are low.
And the youngsters' I-Pads
Cast a gentle glow.
Oldsters 'twit' the youngsters' goldfish memories.
Saying "Back in our day, we'd none of these,
We'd none of these"
