What was Scottish pop rock group Pilot's only UK number-one single?

Pilot were a Scottish pop rock group, formed in 1973 in Edinburgh by David Paton and Billy Lyall. They are best known for their songs "January", "Magic", "Just A Smile" and "Call Me Round".

The 1974 single "Magic" from their first album, produced by Alan Parsons and written by Lyall and Paton, was a No. 11 UK and No. 5 US success. It sold over one million copies, and was awarded a gold disc by the R.I.A.A. in August 1975.

The song "January" gave them their greatest success in the UK, securing the number one spot in the UK Singles Chart on 1 February 1975. It stayed at number one for three weeks. (It also went to number one in Australia where it stayed up top for eight weeks; in the United States, it reached the lower end of the Hot 100.) However, the group failed to make the Top 30 again.

The band's other singles chart successes were "Call Me Round" and "Just a Smile" (both 1975), which each hit the top 40 in the UK and nowhere else.
