The Jools Holland concert has already been cancelled, while the other fat shows featuring Blue, Roxy Music and Simply freakin' Red are waiting to discover their fate.
Apparently a Royal Parks spokesman said that promoters Triple A hadn't yet made a first payment, necessary to get the license, although it was also pointed out that negotiations were ongoing.
More interesting is the rumoured payment by Triple A to an unknown person, who offered them a supposed "twenty-five year licence" with one previous owner - supposedly the Hyde Park-based Star Trek exhibition. If - as alleged - this deal was completely non-legit and the person has legged it with the cash, then Triple A have truly been scammed in a rather impressive manner.
The Royal Parks insist any dispute will not affect Party In The Park, Pride or planned Bon Jovi and Shania Twain concerts.
