It's only February and already there is a lot happening in the ABBA world.

April sees the release of The Visitors Deluxe Edition CD/DVD, with the exciting news that it will contain the first "new" ABBA music heard since the box set Thank You For The Music in 1994. 'From a Twinkling Star To A Passing Angel' promises early versions of the album's closing track, 'Like An Angel Passing Through My Room'.

April also sees a limited edition 12 inch single of 'Voulez-Vous' (extended dance version)/'If It Wasn't For The Nights' on blue glitter vinyl, to commemorate Record Store Day, an annual event started in 2007 to celebrate the uniqueness of the independent record store.

But what at the former ABBA members up to? In January Agnetha made a rare public appearance the annual fashion gala hosted by the Swedish edition of ELLE magazine, where she was presented with the Fashion Icon award. In August Benny Anderssons Orkester will perform a one-off concert in Upsalla, Sweden.

This year also marks 40 years since ABBA's first single release, 'People Need Love', and also 30 years since their final recordings and appearances together. Will we see any special events or releases to mark these anniversaries?
