So sorry to lose you John.  We will always remember you – 

For your unbreakable humour.
Your technical accuracy and tenacity.
The funny stories you would tell, old and new!
The dedication you gave to the task in hand.
Your great sense of fun – even in the job.
The way you held a team together.
Thank you for your willingness to impart knowledge.
Bless you for your steadying hand.

We must thank your family for lending you to us, and hope these condolences may help them to bear the loss.

Cheerio John.
