Hanson offer 'second honeymoon' to persistent UK couple - video
The 'MMMBop' band were the subject of a campaign by groom James Bishop and his friend Chris Douch, who aimed to get the group to perform at Bishop's wedding in July.
The pair started their 'Hanson at my wedding' YouTube mission back in February 2011, sending 461 videos to the band.
Hanson sent Bishop and Douch a YouTube video reply, stating that they couldn't perform at the wedding, but offered them a different present.
They have now offered to fly Bishop and his fiancée Jennie Tripp to Jamaica for their "secondary" honeymoon in January.
Bishop said: "It was a strange feeling because my fiancée doesn't know anything about this."
The pair are due to marry on July 28, meaning that the groom has over a month to somehow keep the gift a secret.
Hanson will fly the couple to Jamaica in January, while also giving them tickets to their gig in the country and pay for their hotel stay.
Douch joked that despite helping with the project, he has yet to be given a similar present, telling BBC News: "At the moment, no prize. I'm still waiting for my video from Hanson."
Hanson have released six studio albums since their breakthrough 1997 LP Middle of Nowhere, which spawned the massive hit 'MMMBop'.
