Susan McFadden and Danny Bayne were last night celebrating the “dream come true” of winning the ITV reality show Grease is the Word.

Meanwhile, the winner of Any Dream Will Do, the BBC One talent show, has recorded a video for a charity version of the title song.

The winners of both contests will now start rehearsals for their West End debuts.

McFadden, 24, from Dublin, who will play Sandy in the musical, and whose brother is pop star Brian McFadden, looked stunned after her victory. She told Zoe Ball, the programme’s host: “The first thing I’m going to do is drink a big bottle of champagne. I have worked so hard to get here.”

Byrne, 19, from Welling, Kent, who will play Danny, said: “It’s an amazing feeling to be here and I never thought I’d get here. I’m just a college boy but I’m really thankful.”

The pair now have six weeks of rehearsals before Grease begins previews at the Piccadilly Theatre, London, on July 25. However, they will not face the critics until the formal opening night on August 8. Some £6 million of tickets has already been sold for the show.

From the other channel, Lee Mead’s single of Any Dream Will Do will go on sale this week to raise money for Children In Need.

Mead, 25, won the public vote to become the star of the new production of Joseph And The Amazing Technicolor Dreamcoat at the Adelphi theatre in London.

His production opens for previews on July 6 and the critics will get their chance on July 17.

Mead has been a professional singer and actor for the past five years and served as an understudy in Phantom of the Opera, Tommy and Miss Saigon. He also danced in Geri Halliwell’s video for It’s Raining Men.

After the result was announced Andrew Lloyd Webber, who had no say in the final decision, which was decided by public vote, said: “Lee may have been an understudy, but he’s never sung in front of me, or sung in front of millions of people before.”

More than three million votes were cast during the televised final on Saturday.

The Josephs were also joined on stage by the winning choir from the Joseph Choir search competition, Brampton Primary School, from East Ham, London.
