Today I found it!

And, even though the campaign is over for this year we are still in the “Twelve Day’s of Christmas” window, so here it is.

From 2012 based on an actual encounter experienced by a young bandsman friend of mine:

Surrendering All!

'Twas a simple job for Christmas
I don't know what else to say
It got me out of the house
And gave me a chance to play!

From gig to gig we moved around
Giving collectors a hand 
Not the most exciting act
But hey, we were in demand!

A time to move from "A" to "B"
We grabbed up our stuff and marched
Maybe a break would be good
Water for those who were parched!

That's when we met him on the way
Panhandler, begger, or thief
My one thought was - " Here we go,
I really don't want this grief!"

Just then he turned the tide on us
And emptying both his hands
Placed his cash in the bubble
And said how he loved the bands!

I'd seen the wealthy pass us by
Not give us the time of day
While this poor soul gave his all
When I'd hoped he'd go away!

There humbled, and yes, strangely warmed
Feet more quickly did move
Renewed in purpose - fired up
I knew I had more to prove!

The twenties and fifties were great
The tens and fives were ok
A new lesson I had learned
The soul determines the pay!

This hobo had given his all
Dollars - not significant
Value - immeasurable 
Example - magnificent!

Please Lord help me give You my best
Ne'er holding back any part
Surrendering all I have
Yes, giving You all my heart!
