A south Norfolk vocal group hit perfect pitch when they sang for rock legend Brian May.

Discord singing group, which is led by Michael Dann, former choirmaster of the Wattisham Military Wives choir, welcomed West End star Kerry Ellis, who has appeared in My Fair Lady, Les Miserables and Wicked, for a workshop at the weekend.

And the star, who is friends with the Queen guitarist and songwriter made sure the group had a day to remember.

Mr Dann said: 'We did a Queen medley and Kerry said 'Brian would love this – I will ring him'. She put him on loudspeaker and we sang We Will Rock You to the legend.

'Kerry said 'I have some people here who would like to say hello to you' and we sang to him.'

Kerry, who is 35 weeks pregnant with her first child, met the guitarist when she was cast as Meat in the West End show We Will Rock You.

After their impromptu performance, the star retweeted the video of the group singing to his 146,000 followers.

Mr Dann, who lives in Scole, near Diss, added: 'It was such a fabulous day. It is a once in a lifetime memory. It will always be the day we sang for Brian May.

He added: 'People are still emailing me about it.'

Discord, which was formed two years ago, meet six times a week.

'The group was formed for anyone who wants to sing. We are not a choir,' Mr Dann said.

'It just breeds wellbeing. We have got some very tragic cases in the group – some people have lost children or have terminal cancer.

'They come in for a couple of hours and when they leave, their worlds have changed. It's amazing.'

More than 80 people attended the workshop at Diss High School on Saturday.

Mr Dann said: 'She was so lovely. She was brought up near Stowmarket and we met when she became patron of the Wattisham Military Wives Choir.

'I am used to hearing these people sing every week but they stepped up another level.'

Last year the group raised £2,000 for East Anglia's Children's Hospices and this year their chosen charity is Cancer Research UK.

The group holds sessions in Diss, Attleborough, Otley and Stowmarket and is looking for new members. For more information see www.michaeldann.co.uk
