7545 Smaklösa           Discovered 1978 July 28 by C. -I. Lagerkvist at Mount Stromlo.
Named after the music group Smaklösa, which performs mainly on the island of Gotland off the Swedish coast during the summer. Celebrating 25 years together in 1998, they made at the beginning of their career the now-famous statement that only cowards rehearse before a performance. The lyrics of their songs are very intelligently written and are even more enjoyable to those more accustomed to the lifestyle and humor of Gotland. The live performances of the group are unforgettable, and the discoverer is very thankful for those he was able to attend during the summer of 1998.
