Mother of two Antoinette Smith disappeared after she and a friend attended the concert in Co Meath in July 1987.

The 34-year old released the lead single, My Guy, on Wednesday and announced that their upcoming album, Hazel Eyes will be out later this summer.

The British singer’s album My Mess, My Heart, My Life will be released on Friday.

Smith, who plays Craig Tinker on the soap, said his last scenes should air in ‘May time’.

Harry Potter and Downton Abbey stars were among those remembering the late actress.

Dame Maggie won over Potter fans as kind and formidable Professor McGonagall.

Councillor Pio Smith said the exploding-devices attack was “one of the greatest anti-terrorist strikes ever”.
