Sommarkrysset is a Swedish television program that is broadcast live from the Gröna Lund amusement park in Stockholm during summer. It was first shown on June 3, 2005.
The program consists of live performances by famous artists in front of a live audience while viewers can call in and win a certain amount of money. To have the chance to win this money, the viewer first has to figure out a word which is derived by entering the answers to questions (one letter in each box) on a piece of graph paper with 5×5 squares like a crossword.
Carlsson participated in Melodifestivalen every year between 2000 and 2007 inclusive, except for 2004, either with Barbados, Alcazar or as a solo act.
