[2] Tomas Ledin started his career in 1972 when his first single, "Då ska jag spela", was a big hit.

In 1979, ABBA member Benny Andersson offered him a chance to record for the group's company Polar Music.

The singer joined ABBA on their 1979–1980 tour as a backing vocalist, but also got the opportunity to sing his own composition "Not Bad at All" during the show.

In 1982, he released the duet "Never Again" with Agnetha Fältskog of ABBA fame; the song reached number one in Chile (in its Spanish version "Ya nunca más") and was popular across Europe.

He nevertheless toured Germany and the Netherlands on a small scale in 1982, and the following year, he played in front of 60,000 people at the Olympic stadium in Berlin, in a show with other international acts.

In 2000, 260,000 copies of his compilation album Festen har börjat (samlingsalbum) were sold in Sweden, which meant he was awarded three platinum records there.
