Just judging by the tracklisting No Security is certainly not a typical "greatest hits live" disc. If anything the tracklist may be a bit too idiosyncratic.
Did you splurge on the deluxe Charlie Is My Darling release? I am mighty tempted but that sucker ain't cheap!
No, I can't say that I have. But so much money for a box set of live recordings from 1965? I'm not sure. You probably can't hear half of it because of the screaming girls. It's probably a bit like Got Live if you Want It!, their first live album. Good as a historical document, but not prime Stones - at least not as a live band. But the movie might make it worth it.
I have a slight preference for No Security over Still Life because of it's idiosyncratic track list myself. As I said earlier, how many recordings of Jumpin Jack Flash, Honky Tonk Women or Satisfaction does one person need?
