The day the music died...

According to the Jewish Chronicle, a bunch of British rabbis have signed declarations banning their followers from going to upcoming concerts by two well-known Jewish singers. The reason: their concerts create an “immodest environment.”
Were they referring, perchance, to Madonna (just kidding. She’s still not Jewish)? Lenny Kravitz? KISS lead singer Gene Simmons?
Nope.
Haredi stars Avraham Fried and Mordechai Ben-David. Those wild and crazy guys!
Note that the ban took place after the organizers promised to provide separate entrances, exits and seating for men and women.
I guess the rabbis are instituting a new chumra: instead of the 3 weeks, let's just have the 52 weeks...

UPDATE: One of the organizers of the Avraham Fried concert thanks people for attending "even after what the rabonim said about it"; The Manchester Jewish Telegraph reports that the rabbis banning the MBD concert distributed an article explaining that "the intention of "frum singers" is "only to make money and they ignore the terrible negative influence that they are bringing with their music. Even if it is not intentional, it still takes control of the minds of young fans." (Update via Blog in DM)
