Performing a farewell gig in the band's home city will be nerve-wracking, Tony Iommi said.
"We're all nervous really," he said but added preparations had gone well.
"People are coming from all over the world and I just can't absorb it."
Tommy Iommi says the gig will be different to anything the band has done before
Singer Osbourne is only expected to sing four songs because of health issues and Iommi explained that rehearsals had been hard on all of Sabbath's classic lineup.
"I wouldn't say it's been easy, it's been tough, because none of us are getting younger and to stand there for a couple of hours is tiring," he said.
"This is totally different from anything else we've done, you know we've played for 300,000 people but this is nerve-wracking."
"We're never going to do this again, this will be it," he confirmed.

There's lots of black, unsurprisingly, and everywhere you look there are Black Sabbath t-shirts, or t-shirts paying tribute to other metal bands performing today.

Stefano has been sleeping outside Villa Park since Wednesday
This is a man who has shown serious dedication - his name is Stefano di Fiore, he's 27 and lives near Rome, Italy.
He's first in the queue to get into Villa Park.
He arrived on Tuesday and has been sleeping outside the stadium since Wednesday afternoon.
"It’s been rainy and cold, but I did it for Ozzy," he said.
"This will be the best concert of my entire life."
Jorgen from Sweden is third in the queue
A couple of spaces down, third in the queue, is Jorgen Gamelius, 55, from Sweden.
He arrived yesterday at 2pm.
"This is history," he said.
"I saw him in the 80s and 90s. I have seen him 8 times in total.
"Black Sabbath is the only one that has this sound."
Jack Osbourne, son of Ozzy, said a documentary about his dad's life means something different now.
Fans from all over the world gathered at Millennium Point on Friday to watch The Nine Lives of Ozzy Osbourne, with host Ed James saying there were so many questions fans did not want to leave.
The film was made a few years ago, and was shown on TV after an original premiere at the South by Southwest festival was cancelled due to the Covid pandemic.
"It was kind of early on in this next phase of my dad's life when we did this documentary," Jack said.
The documentary about Ozzy's life got its world premier in Birmingham last night
"Watching it here in Birmingham with what this weekend means... this whole weekend has been emotional, but it kind of adds to it."
Mr Johnston added: "It sort of feels like this is the right place to actually show it on the big screen in front of all the fans and Ozzy's hometown."
"It makes it that much more special."
