The latest example of this was Pantula Rama's concert at Unnati in Bangalore.... a supremely classical concert with a phenomenal Bhairavi and she somehow felt the need to include SB in the thukkada section! Thank god she followed that up with a purely carnatic Athana thillana... I would have hated to walk away at the end of the concert with the SB piece as the final one.
On an every more tongue-in-the-cheek note ... the way the rash of SB is proliferating, soon enough most rasikas will assume that it is a rule to sing SB at the end of a concert.... some day, we will have a discussion wherein the "traditionalists" will be berating some poor performer for not including SB in his / her concert ... "How dare s/he do something like this? I mean, does s/he have no respect for traditions and our classical values?? X("
