There have been 1383 UK chart single number 1s since 1952.
This was the first hit song written by Paul Evans. When specifically the Everly Brothers were around, everybody wanted the Everly Brothers. They were superstars. So we wrote a song for the Everly Brothers. It was 'When,' but the Everly Brothers were almost impossible to get if you weren't Boudleaux Bryant and his wife Felice. They got the Kalin Twins to do it because Decca, who did they think of when they heard a duet on a demo? They thought of a duet, that's just the way it was in the business at the time. The Kalin Twins were the first act with twins to make the Top 10 in the US or UK.
