Last year, Brian Johnson discussed how his famous hat came to be part of his signature image. Prior to joining AC/DC, Brian was the singer of a well known UK band called Geordie who enjoyed success including having four top 20 songs in the country. After Geordie disbanded, Brian found a job working as a window fitter and didn't want to be recognized from his previous stint, as Brian told Popeater.com “People just assumed you were an instant millionaire. It wasn’t the case at all. We didn’t make much money and when it all finished I was worse off than when I went in. I had to get a job quick, so I took the first thing I could find. I thought being a windshield fitter on the motorway was a good idea because nobody would see me. But just in case I pinched my brother’s sports car driving hat, and I pulled it tight over my eyes so nobody would say, ‘Weren’t you the lad that was on television?’”
Brian says it didn't work, and he was still recognized despite his attempt to hide his identity. He continued music, singing in a band at night, "...I had a band at night and we were very popular in the pubs. I kept wearing the hat because I’d come straight from work and run onto the stage. It became a trademark – it became my lucky hat.”
In 1980, Brian got the job with AC/DC, and the rest of the band convinced him to keep wearing the hat as 'it had some style', as he had planned to stop wearing it at the time, and has been wearing it ever since.
