Veteran crooner Barry Manilow wept on stage as he accepted a standing ovation at the opening night of his musical.

The singer fulfilled a life-long dream by writing the music for Harmony, based on the true story of a group of German singers, but he faced a difficult journey bringing the show to the stage as the production was hit with numerous delays and setbacks.

After brief previews in 1997, Harmony finally opened in Los Angeles on Wednesday night (13Mar14), and Manilow was visibly overwhelmed when he was invited up to the stage at the end of the performance.

He was seen wiping away tears as he thanked the cast and crew, and added, "What do you say when a dream comes true?... This success is so emotional and exciting."
