Maybe its totally wishful thinking, but to me, the person (bubble) on the left, closest to whomever took the picture, looks like Nick Seymour... the other person on the right (blue trunks) , could be Matt.
It's true that there is no confirmation, but there's no reason why it can't be Crowded House (and family) in the picture.
Neil's upcoming solo dates, in no way have to be related to whatever album he's recording these days. Realistically, and based on history, this album probably won't see the light of day until much later in the year (if we're lucky).
