OK Woopie
It goes like this

........
Late 82 Brad, Rudy, Don, Tommy
December 82 the band are due to arrive in Britain for the UK leg of the 'Speak of the Devil' tour, BUT Rudy Doesn't show up!
So the Band is Brad, Pete Way, Tommy & not Don Airey for these shows in Europe but Lyndsey Bridgewater who was last seen in the band in December 1981 In the Euro 'Diary' tour shows. This line up of Brad, Tommy, Pete, Lyndsey play the last gig as this line up on Dec 19th in Liverpool.
On Jan 16th 1983 in Helsinki, Finland the band has a new line up!
Jake E Lee, Don Costa, Tommy & Lyndsey
They get back to the USA in Feb but Lyndsey is replaced by Don Airey and in May 1983 Don Costa is replaced and the line up is like this
Jake, Bob Daisley, Don, Tommy
In November 83 Tommy is replaced by Carmine Appice and then Tommy Replaces Carmine in March 1984!
The band remains in this Jake,Bob, Tommy & Don until Jan 1985
THe last line up Bob,Jake, Tommy & Don in my oppinion was the last great line up Ozzy had
I hope that makes sense and helps
