But that was only a minor blip in a set that yielded the beautifully observed close harmonies of Cosy Prison, a nicely fluctuating Manhattan Skyline and a brilliant rendition of the crowd pleaser Hunting High And Low.
There wasn't much chat from a sober Harket, leaving his band members to whip up the crowd during the Living Daylights singalong with shouts of "Do it for Kenny Dalglish!"
The 007 tune was a highlight during 120 minutes of music that inevitably pandered to the audience's yearning for Take On Me and The Sun Always Shines On TV.
Some of the best moments came from some of a-ha's lesser known singles like the stomping I Call Your Name, the rocky I've
Been Losing You and the barnstorming Summer Moved On, the song that saw the band reborn in 2000.
Despite Harket's puppet-like behaviour, the voice - whether deep, rich baritone or screeching falsetto - borders on the staggering.
