Marty Goetz is an American. He's a musician: a pianist, singer and songwriter. He's also Jewish - so Jewish you would find it difficult to imagine how he could be any more Jewish.
He grew up in an area where 90 per cent of the people were Jewish. If he moved out of the area, his mother would warn him: "there are antisemites out there." He had to move out of the area, however, to complete his education.
As a young man, he formed a musical act with a Methodist called Bert. The trouble began when Bert went to another church and was born again. From then on, he preached about Jesus to Marty, which made Marty very angry and very frustrated, because Jews don't believe in Jesus.
What happened after that you can hear in Marty's own words in this video here.
