I finally got these words from a morris dancer friend. They're by Ian Robb:

Farewell old friend, it's time to go
You must be on your way
Do not let the parting grieve you so
Though dreary seems the day

Chorus:
And I'll sing Alleluia,
And you'll sing Alleluia,
And we'll all sing Alleluia
When we arrive at home

No saint you were while on this earth
You trod your path so wide
For saints do seldom venture forth
For fear they stray aside. CHO

If God there be some Pharisee
Of unforgiving ways
You must look for him for you must seek
To brighten up his days CHO

And when at Peter's gate you stand
With sins of flesh and wine
One son of his will take your hand
And lead you in to dine CHO

For friends may join and friends may part
And friends be born and die
Each song remains within the heart
Each spirit ever nigh CHO
