"Isa Lei" is the beautiful song of farewell from Fiji, sung to departing visitors.Melodic and inspiring, its sweet notes rise in layers of hymn-like stanzas. The Fijians have plenty of practice singing on Sundays in church and one has only to attend a service to be wowed by their melodic harmonies. Their farewell song to you is therefore certain to arouse emotion. It was recorded in 1967 by the Australian folk singers The Seekers on their album "Roving With the Seekers." The group continues to perform and has just had its 50th anniversary, marred slightly by Judith Durham's recent ill health.
