Acrobatic Rock And Roll

-------------------
Even if the Tielman Brothers and the Beatles had never shared any given time, the influence of Tielman Brothers can not be neglected. George Lipsitz in his book Dangerous Crossroads (1998) stated: "The Tielman Brothers rock and roll and stock performance acrobatic attracted considerable attention. They played guitars and basses with their fingers and teeth. They sometimes worked against them behind the head. This action gave them the popularity in Europe until they got their own fans in Hamburg, Germany. A place where they could exert an important influence on early career of the Beatles!

Yes, the beginning is correct, but there are other errors.

1) Put quotation marks around the name of dangerous crossroads.

2) Check your quote from the book. Is not there an apostrophe after Brothers?

3) What is the end of the quotation from the book? If the end is "... The career of the Beatles", then you can not change what the author says.
