Many thanks jbaent! Much appreciated.
I had tried to find the durations by myself before bothering you, but I only have a YouTube music account, which only shows the 3 released tracks.
There are good news and bad news:
-Good news is, TOL from OTN seems to be complete, with intro and band introductions. The duration is similar to Rotterdam 30/05/1992, even 18 seconds longer, so a bit of clapping before and after.
-Bad news is, 1) TOL from Alchemy seems butchered, with this length either Mel's sax intro or Mark's speech about the Spanish city is cut. No way to have both... and 2) MFN and WOL are more or less the same length than the original, so the opportunity to restore MFN intro and end drum solo is lost too!
