I consider it very wise to give the people at large what they want. At the same time I think that is just as wise not to give the people all that they want. Give them part of it. That is, don't give them so much of it. Warhorses should be a mere privilege to experience, not the stable diet. Make people come back for more of something else of it - on another concert in some other city, possibly on another tour
. Especially, make the journalists that create expectations in advance, themselves eagerly wonder which warhorses - by then not warhorses anymore, but special treats - it would be their privilege to experience. Turn arrogant journalists into enthusiastic listeners, spreading the message. Make even the die-hard fans crave for the songs that now make them frown in front of their PCs.
(Presented as a way of thinking. Wishful thinking probably, but then as a consequence, more new tracks and more rareties would be obtainable as well. Such as "Tell Me", Good Times, Bad times", "Long, Long While". Nice try?)
