Rare Japanese Solo Promo 7 Inch On Ebay

I wasn't aware that this even existed. On Ebay you now can find a Japanese 7 inch promo featuring "Radioactive" from Gene's solo album and "Don't You Let Me Down" from Peter's solo album. The weird thing is that this promo 7 inch has got three different sleeves.
