I think the song that Ray is referring to is possibly 'So here's to you'. It uses the phrase 'parting glass' in the chorus.

'When first we met, complete total strangers,
We didn't know if we could be friends.
How soon we've come to know each other,
So now I know we will meet again.

Cho
So here's to you and our time together,
I'll share with you now a parting glass,
And bid adieu with a smile and laughter.
Our time apart will be short and pass.

We've talked of dreams and the good tomorrows,
Of yesterdays with their dark despair.
We've had our share of love and sorrow,
So now we part as friends who care.
Cho

A long long road now lies before me,
And fate will lead me where it will.
All throught the valleys and over mountains,
I'll not forget and remember you still.

Alan Bell 1978
