The Dallas rehearsals (Exile album by DaC is by far the best version sofar. Contains different songs in comparion to the 1CD Empress V. version which is also worth while. Like you are part of the studio staff with the Stones rehearsing around you. Also the re-released Lyon 76 version by DaC is great. Completely excelent soundboard this time. Glasgow 76 is for the collectors but better than the LP version. Both Frankfurt 70 gigs are acceptable quality. Hamburg 70 I will purchase tomorrow evening in case the DaC shop is open.
