I saw DP with Joe Lynn Turner. I wish I hadn't.
I heard the bootleg recording of that gig, Hebrew introduction and all (it was a radio show I believe), I think it was the last one of that particular line-up and the writing was on the wall already - and not because it took place in the Holy Land! Glover, Lord and Paice + the management wanted Gillan back, Blackmore was the only one loyal to Turner, but losing his once iron grip on the band. The planned US tour had failed to ignite audiences and was shelved; the Purple organisation wasn't making money. Covert advances were made to Blackmore with extra money and a future Rainbow reunion to coax him into letting Ian Gillan return while no one was talking to Joe. Not a happy gig then.
I had seen them at the second Hammersmith gig in London some months before (they played three nights there), that was a good one and the line-up then stll thought it had a future. Blackmore was obviously enjoying Turner's singing & company and therefore at ease with himself, something he very rarely was with DP on stage throughout their career. That gave the gig a Dire Straits'y atmosphere, but it was musically fulfilling if you ignored some of Joe's more cringeworthy mannerisms.
