“What neither Elvis nor his fans knew at the time was that, throughout his client’s touring career and in spite of vast sums he was being offered, Parker habitually turned down all offers of international tours because he was in fact an illegal immigrant, and feared that if he tried to leave the country he would be exposed, and might be deported back to his native Holland.”
Come to think of it, Elvis not touring Europe is very strange. I think you’re right.
The only time he played overseas was when he was in the Army stationed in Germany. He actually didn’t stay very long in his barracks. He rented a few rooms at two different hotels and then rented a house and some of his musician friends flew over and sometimes they would have a gam session at eh house and allegedly thye went up on stage at a local bar and sang a couple of songs.
