Eurovision Song Contest 2021

In 2021 Måns was a part of the Interval Act again. Due to the pandemic, the Interval Acts were recorded in advance that year. In addition to Lordi and other winners, Måns sang his winning title on "Rock The Roof" on a roof high above Rotterdam.
The 65th Eurovision Song Contest 2021 took place from May 18th to 22nd in Rotterdam, the Netherlands. The motto was "Open Up". Due to the COVID-19 pandemic, however, there were some adjustments done to the competition. For example, in addition to the live performances, recordings of the participants were made in advance, which could be broadcasted if necessary.
Most of the interval acts were also pre-recorded. So was "Rock The Roof", in which former ESC participants presented their songs on the roofs of skyscrapers in Rotterdam at night. Måns started this interval act with his title "Heroes", and the stick figure MP was also back again.
The following participants can also be seen on "Rock The Roof": Lenny Kuhr (De Troubadour, 1969), Getty Kaspers and Teach-In (Ding-a-dong, 1975), Sandra Kim (J’aime La Vie, 1986), Helena Paparizou (My Number One, 2005) and Lordi (Hard Rock Hallelujah, 2006).
