Try Banks Music in York http://www.banksmusic.co.uk/
I buy all our band music through them as 9 times out of 10 it's cheaper than going through the publishers. If you actually phone them they'll willingly do all the searching to find a particular piece and then order it in for you
SHARE MY YOKE
Music and lyrics by Joy Webb
Arranged for brass band by Ivor Bosanko
When I'm tired and nothing's going right for me;
When things I've counted on just do not come my way;
When in my mind the thick grey folds of doubt arise,
It's then I seem to hear him say:
Share my yoke and find that I am joined with you.
Your slightest movement I shall feel and be there too!
Share my yoke and come the way that I must go!
In our "togetherness" my peace you'll know;
The world beholding us will see it so!
When I'm perplexed and no one's understanding me;
When even safest thoughts collapse in disarray;
When I've lost the things that always seemed so sure,
It's then I need to hear him say: (repeat chorus)
When I'm alone and nothing's getting through to me;
And isolation that increases day by day;
When closest friends can seem a thousand miles away,
It's then I long to hear him say: (repeat chorus)
