Warren Zevon, I believe, is half-Jewish.
Not sure just how successful ‘Werewolves of London’ was, but it had to at least crack the top 40.
I am pretty sure that Mike Gordon and Jon Fishman of Phish are Jewish…but I do not know if any of their records have cracked the Top 40.
I definitely remember hearing Jon sing a Hebrew folk song (“Yerushalayim Shel Zahav???” I prolly spelled it wrong).
Artie Shaw.
How can you forget Kinky Friedman & the Texas Jew Boys ? (Well, some of them were Jewish).
Ben
My bad, Kinky never made it to the top 40. (But should have)
Mick Jones of the Clash was Jewish according to the mother rule. He had 3 or 4 top 40 hits and maybe one with BAD.

There are more here, although I’m not sure about all of them.
