TAIPEI - Taiwanese pop singer Teresa Teng returned from the dead on Saturday night as a hologram to duet with Taiwan crooner Fei Yu-ching.

They sang her songs, What Do You Have To Say and Wishing We Could Last Forever, at a Taipei Arena concert commemorating the 20th anniversary of her death on May 8, 1995.

The concert organisers, the Teresa Teng Foundation and the Teresa Teng Corporation, are spending US$15 million (S$19.9 million) to create the virtual Teng performing 15 of her hits, dressed in different costumes.

The digital Teng on Saturday performed only six of the songs including The Moon Represents My Heart and Tian Mi Mi, while mimicking Teng's movements such as picking up a skirt and pulling off a cape. Wishing We Could Last Forever was performed as an encore.

The concert, which featured three other singers performing Teng's hits, will go on tour, Apple Daily reported.

A Shanghai stop in August will become the songbird's "first performance" in China.
