It's not just the "count in" that is Sultan-ish, also there is the grove, tempo, rhythm, few drum fills and guitar licks etc...but to "kill"? I don't think so...would it be a nice replacement in the setlist perhaps? Maybe...
Non the less, I'd always take songs like Beryl prior previous two early released ones like Get Lucky and Redbud Tree, so I got the very good feel about the Tracker, can't wait
But I'm also not so sure that technical difficulties of the "the twiddly bits" or guitar skill in general, played the part in dropping out SOS on Privateering tour. There are many much more difficult to play guitar licks on other songs which Mark still plays very well. I found the last Telegraph solo much harder than "the twiddly bits" per example. After all, "the twiddly bits" are not so hard to play at all. As a player I can assure on that. Plus, I'm yet to hear a live record of SOS from 2013 tour where are any troubles with "the twiddly bits" can be heard...but my "theory" on that topic goes forward that something else in the band not as quite as it should. Comparing to GL tour records of SOS perhaps...those from 2013 are quite less energetic. If I must do the ugly job of pointing fingers, I'd address it to the drums...
