I would like to see the concert canceled, in favor of a performance of shiras ha-Leviim on the Shabbos before the concert, with Moshiach, so we do not need HASC anymore.
If he should be delayed anymore chas vesholom, then yes, from my limited experience with HASC concerts, Fried/Helfgott would be perfect, with some sort of appearance from Lipa.
