its quite possible that UW's Management sent out this promos to Pete Tong, with an accompanting 'sticker' or something and as such he assumed it was from a label, rather than the management name...this often happens with promo's being distributed by various sources, and sometimes unlabelled promos get 'written down' as being on the promotors 'label'...

but currently Sunday Club is the management of UW, as you pointed out, and until someone official says so, i think these releases will be on UW's own UWR label, whatever that may officially be called...
