The only song I don't care for too much is Children of the Night which always felt like the filler track to me.
Maybe it's just me - Chad would back me up if he was about - but aside from a couple of weak tracks I don't mind Slip of the Tongue at all - and for the record Coverdale and Vandenberg wrote that whole album (aside from the Fool For Your Loving cover) and Vai was a rather last minute replacement due to Vandenberg's hand injury and Vivian Campbell leaving. He had the unenviable task of taking Vandenberg's songs and , if memory serves correct , submitting tracks to Coverdale for approval with little to no studio time as a band. Under the circumstances I think he did a pretty remarkable job.
I'll happily stick up for you in Chad's absence. I like Slip, mainly for vai's involvement.it would have been average without him.
As for 1987, I loved it at the time and still do I guess but it's been overplayed. I prefer live in the heart of the city, slide it in and even saints and sinners though they lacked the polish in the production department that 1987 had. Cov's voice was going by then too.
As for Sykes,that first blue murder was very good, his stint with lizzy was good, but all those false harmonic squeals get on my tits after a while.
I really haven't enjoyed much of whitesnake's output since slip.
Live I always enjoyed the shows, even more recently when his voice was really not up to the job.
