This record saw some contributions from Czesław Niemen, who played his Moog synthesizer psychedelic parts in a majestic rock suite called "Szalony koń". Clocking over 19 minutes, this track took a whole B-side of the long play. The radio hit "Sen o dolinie" as well as "Memu miastu na do widzenia" were not placed on the album. The first one was rejected by the record label, because it was a cover of a foreign artist and the latter was written by Lipko solely (there was a sort of deal among the band members, they wanted only songs written by Cugowski and Lipko together on the first album). The release became a success and the band went on a tour to East Germany. There, few German versions of band's greatest hits were recorded. There were plans to release an album in Germany, but they failed as Cugowski missed a recording session. A second attempt failed, too, because of the exhausting tour that ended just before. In 1976 another band's record, named "Przechodniem byłem między wami" was released. It did not repeat the success of its predecessor. After the release, Cugowski decided to leave the band and start a solo career. He was replaced by Stanisław Wenglorz, an ex-singer of Skaldowie. He has only appeared on few records ("Rozmowa", "Kula nocnego światła", "Ślady na piasku", "Życiowy numer"), then unreleased and quit soon after. The next vocalist became Romuald Czystaw. The band's line-up has changed many times over the years. Since 2005 the band members are:
