There were scenes of near hysteria at The BIC on Friday night, as a packed house gathered to say goodbye to one of the most popular and enduring bands of the last two and a half decades, Norwegian supergroup A-Ha.

There were screams, tears... but enough about me. The rest of the crowd loved them too.

I've been a fan since I first saw them perform live back in the early 90s. I'd always loved their music, but seeing them on stage is something else again. And it's not just about the cheekbones.

While even the best of vocalists can waver away from the safety of the recording studio, the divine Morten Harket seems to just get better and better. One minute deep, mellow rock god, the next high and pure as a choirboy, his voice is a remarkable instrument that's been key to A-Ha's distinctive sound, helped by the brilliant songwriting of Paul Waaktar-Savoy.

Their farewell show was a superb mix of old favourites and newer, edgier sounds, kicking off with The Sun Always Shines on TV, and followed by one of my favourites - Move to Memphis, with its echoes of The Doors. Other highlights included Stay On These Roads, Don't Want To Cry No More and Hunting High And Low, which had the audience dancing and singing along.

I'd heard about that record-breaking high note on the poignant Summer Moved On, which lasts about three bars, and this time round Morten appeared to hold the same note for 27 seconds. Spectacular.

There could only be one song for their final encore - the iconic Take On Me, which had started it all, and which had an ecstatic BIC crowd on its feet.

But for me the highlight came earlier, when they turned down the lights, left the backing musicians behind, and the three of them - Morten, Paul and Mags - played their newest (and last) song, Butterfly, Butterfly, with just Morten on vocals, Paul on acoustic guitar and Mags on piano.

This must have been how they began, just three superbly talented musicians, with no special effects to hide behind. And that's how I'll always remember them.
