Pop Star for a day type experience gift voucher. A few of these about, but with the discount code this seems pretty good. My sister went to this place in London about a month ago (big X-factor fan) and she loved it, they actually made her sound pretty good (not easy). They now have 10% off on the site and she has been sent a discount code for a further 30%. Seems cheaper than BuyaGift @ £99.
Note: London only, so no good for you northern types.
