Black Sabbath are topping the bill at an outdoor show in London's Hyde Park this summer - and they hope they will get royal approval.
The veteran rock group is the latest headline act to be announced for the British Summer Time festival, and will play the event's opening night on July 4.
Osbourne reminisced that when he first went to London he was impoverished and "spent the advance I got for the first album on a new pair of shoes and some Brut aftershave".
"Returning almost 50 years on we are doing a bit better for ourselves, so I may even splash out on some new aftershave before taking to the stage at Hyde Park ... We are beyond honoured to be allowed to put on a show and hope that the royals will enjoy it," he added.
Reunited heavy metal band Black Sabbath have landed a hat-trick of prizes at the Classic Rock Roll Of Honour awards tonight.

Guitarist Wilko Johnson who announced earlier this year he has terminal cancer and is refusing treatment - took the "innovation" prize from the magazine.
Black Sabbath's comeback album took them to number one for the first time in 43 years.
We're still revelling in coming back with this. I don't want to promise anything to anyone. It took us long enough to do this, and we can't wait another 43 years to have another number one. If it comes to pass we don't make another record, then I can rest easily knowing we finished things properly with 13.
