Most of the audience were on their feet and dancing away by the time Abba tribute act Arrival from Sweden reached the climax of their first night show.Tuesday night's concert at the Fairmont Southampton Amphitheatre opened this year's Bermuda Festival of the Performing Arts.The choice of an all-seater venue for the staging of a band whose set list is comprised almost entirely of the liveliest and best-loved dance tracks of the 1970s and early 1980s was odd.However that soon became immaterial as more and more of the audience left their seats and started to shake their stuff in the aisles and around the edges of the room.The look-a-like group, dressed in authentic Abba-era stage outfits, encouraged people to get up and enjoy themselves.Just like the original Abba, the tribute band hail from Sweden and they put together a performance filled with the hallmark joy and verve that made Agnetha, Benny, Bjorn and Anni-Frid such a global phenomenon between 1972 and 1982.Singer Jenny Gustaffson, who performed as blonde-haired lead singer Agnetha, turned in the performance of the night midway through the concert with a dazzling rendition of the poignant ‘Winner Takes it All'.She had moments earlier left the stage to change into her second costume of the night. Then, as her singing partner Victoria Norback (Anni-Frid) departed to switch costumes, Ms Gustaffson produced her mesmorising, note-perfect take of one of the most heartfelt songs in the Abba canon. Keyboard player Rolf Ivraeus (Benny) wrapped up the song with a perfect piano flourish.Up to this point in the evening the band had competently worked their way through Abba favourites such as ‘Voulez Vous', ‘Gimmie, Gimmie Gimmie', ‘Knowing Me, Knowing You' and ‘Supertrouper'. But the huge show of appreciation that followed ‘Winner Takes it All' elevated things to a new level. Arrival, who included within their musical line-up original Abba studio bass player Mike Watson, got the audience on their feet at the end of the evocative ‘Chiquitita'.However it was Abba's breakthrough ‘Waterloo' the 1974 Eurovison Song Contest winning number that propelled them to fame which led to many in the audience leaving their seats and surging towards the open space in front of the stage as itching dancing feet all around the amphitheatre could no longer be controlled.What Ms Gustaffson lost in being unable to move as freely as normal around the stage, due to her pregnancy and jarring her back during the soundcheck, she made up for with a confident vocal style that did justice to the classic songs. Fellow singer Ms Norback was likewise a joy to listen to, and she kept the dancing action going on stage. With guitarist Staffan Birgersson filling in with backing vocals and a few well-placed riffs, it was quite possible to suspend reality and believe that the original Abba were up on stage once again.The remainder of the evening took on the atmosphere of a disco from the late 1970s as dancing people could be seen all around the room. The finale, the brilliant ‘Dancing Queen', topped off a memorable night that allowed those present to escape the cares of today and recall the fun-filled simple joys of yesteryear. The sellout show was a perfect opener for the Bermuda Festival.
