In a tribute to Jonh Purdy, at the start of his book, he wrote these words

"And now my time is past and gone and my singing it must cease,
Just lay me down in country ground for to find eternal peace.
And there's just one thing before I go with you I'd like to share,
That peace for me will only be when song is in the air"

I asked Dave for permission to use this as the final verse of this song, to which he agreed.
