Before he took to the Mission Concert stage Barry Gibb was delighted to hear that the great crowds enjoyed adding their vocal chords to few songs.
And of course they did on Saturday night as he ventured into a set-list of songs which embraced the musical legacy of the Bee Gees.
It was on the 21st of the 26 songs he and his band of family and friends turned in that the voices from the valley really caught his attention.
The song 'Words' means a lot to him, so when the audience roared into the final chorus he stopped and listened.
He tried to complete the song his way twice but the audience took over.
Then he smiled and said "it's my turn" and completed it in a voice which possessed all the power and emotion it had when it emerged more than 40 years ago.
The show was powered into life by vision - visions of the early days of the Gibb brothers.
Then the images were re placed by the words 'Please Stand By' - and a bass rumble thundered across the hillside and the crowd stood and began to raise their voices, and glasses, to the arrival of Mr Gibb.
"How you all doing ... alright?" he asked.
When he and the sharp band launched into 'Jive Talkin' the voices rose, and so did the dancing bodies.
The familiar songs just rolled on.
With a back catalogue that stretches to hundreds of fine compositions he couldn't do them all, but his selection was pretty well on the mark.
'Lonely Days' got the voices up again, and 'You Should be Dancing' got the bodies up im mediately afterwards.
Then the beautiful 'First of May' which clearly underlined that his desired tipple of rice wine must work on the vocal chords - the notes were sub lime.
