Being Jewish myself, "Jews Who Rock" by Guy Oseary is an excellent idea, and it would entertain everyone who thought that "Jew" and "rock and roll" don't go together. That is, if it could be entirely trusted.
The sections about the personalities who actually are Jewish are very good, with some great quotes and interesting facts (who knew that Paul Stanley once worked in a kosher deli?), however, we are let down with the mistakes and omissions.
However, there are some major errors. John and Michelle Phillips of the Mamas & the Papas and Walter Becker of Steely Dan are listed. They do have a Jewish band member (Mamas Cass Elliott and Donald Fagen, respectively), but these people are not Jewish and need more research. Judah Bauer, the guitarist for the Jon Spencer Blues Explosion, is not Jewish either, and I'm not too sure about drummer Russell Simins.
It does not have any information about parentage. Twisted Sister's Dee Snider is listed without any information on parentage, and so are Carly Simon, Robbie Robertson (The Band), Mark Volman (The Turtles) and Warren Zevon. All are Jewish on their father's side.
There are also some prominent omissions - Scott Walker (The Walker Brothers), Phoebe Snow, Paula Abdul, Tiny Tim, The Tokens, Keith Reid (Procol Harum), Jay Black (Jay and the Americans), Country Joe and the Fish, Marianne Faithfull, Mick Hucknall (Simply Red), Graham Gouldman (10cc), Chris & Rich Robinson (The Black Crowes), Jay Kay (Jamiroquai), Natalie & Nicole Appleton and Mel Blatt (All Saints), Rachel Stevens (S Club 7) - I could go on. I will excuse the last five since they are not household names in the US.
It also touches upon some mebers of a particular band and not others; these include the J.
