In the army perhaps.
Perhaps, but National Service had ended in Great Britain. Here's what Paul said about that in Uncut
March 2012:Paul McCartney on The Beatles’ early daysWhat was the turning point for you?
"The end of National Service. Not just for me. For anyone of a certain age. Without that, there could have been no Beatles. To me, that was like God opening the Red Sea for Moses and the Israelites to come pouring through. It was like God decreed there would be no National Service. Well, that was extremely handy. Nice one, mate. That certainly changes things. It meant that we were the first generation for so many years that didn’t have that we’ll-make-a-man-of-you threat hanging over them. We weren’t going to be threaded through the system like so many before us. You have to remember that we’d watched all that happen to Elvis. Because, y’know, the army had kind of ruined Elvis. He’d been this ultimate rebel figure who we’d all worshipped. Then they made him cut his hair and he had to call everyone 'sir', and he was never really the same again. You can imagine that going into the army would have done it for us, too. Before we knew what was happening, we were like errant schoolkids off the leash. As The Beatles, we went off to Hamburg, which was still a bit black and white. But it was getting a little brighter. Then we came back to England and we were a proper working band. So we’d avoided this dreadful thing of having to get a job. Now we’d had a little practice and we were getting, well, quite good. And the colour began to fill into the whole thing. By that time, we were beginning to make a bit of a splash. We knew that we had a chance of making it."
And about Ringo:You (and John) were like two sides of the same person?
"Well said. But the sides would switch. On the surface, I was very easy-going, always accommodating. That came easy to me. That’s how I’d been brought up. But, at certain times, I would very much be the hard man of the duo. At certain moments, I could bite. But that would be when no one outside the group was watching. John would allow me to take that role because it enabled him to drop his guard and be vulnerable. On the surface, he was this hard, witty guy, always on hand with a cutting witticism. He appeared caustic, even cruel at times. But really he was very soft. John was very insecure. He carried a lot of that from his upbringing, what with his father leaving when he was five. Then, of course, we’d both lost our mothers so we had that in common. Ultimately, we were equals. All The Beatles were equals. If things got too deep, Ringo would crack a one-liner and that kept us on a level. If things were getting too sentimental, John would harden it up. If John was getting too hostile, I’d soften it down. Then George was always on hand with his own kind of unique wisdom."
