In 1979 the multi-platinum album "Discovery" was released, reaching number one on the UK Albums Chart. Although the biggest hit on the album (and ELO's biggest hit overall) was the rock song "Don't Bring Me Down", the album was noted for its heavy disco influence. "Discovery" also produced the hits "Shine a Little Love", their first and only no. 1 hit from 1972 to the present with any of the four major or minor US singles charts on "Radio & Records (R&R)", "Last Train to London", "Confusion" and "The Diary of Horace Wimp". Another song, "Midnight Blue", was released as a single in southeast Asia. The band recorded promotional videos for all the songs on the album.
