Czech band, Lake Malawi, is on stage. The lead singer is jumping around wearing, yellow sweater. Backing vocals are very strong. Lead jumps around, while the camera shows him and the other band members in colorful squares. Red and Yellow are the colors this year for the Czech performance. Ironically this song starts with "Can you hear it?" after the Cypriot mute performance. yes, we can hear you, dear.
