A rock and cabaret band whose name means "Jan's Spring", playing at the "Pod Ręką" club. It was formed in 1966. It brought psychedelic music with a varied range of instruments to the music scene. It was active for 6 years, making several radio recordings in that time.
     In December 1970 the band appeared at the Sala Kongresowa (Congress Hall) in Warsaw together with Niebiesko-Czarni and Tropicale Thaiti Granda Banda.

 Line-up:

lead guitar, vocals - Jerzy Wójcik (1946-1989)
rhythm guitar, piano, viola, vocals - Jacek Ukleja
bass guitar, vocals - Jerzy Kołacz / Paweł Partyka / Jacek Szepan   (d. 2019)
piano, vocals - Rafał Marchewczyk
Claviset, organ - Piotr Walewski
percussion, tambourine, vocals - Ryszard Antoniszczak (1947-2021)
sound engineering - Jerzy Kołacz / Paweł Partyka

     The line-up was expanded as needed. For the larger-scale psychedelic shows it was joined by: Krystyna Święcicka - vocals, Bogna Idziak - ocarina, Piotr Łopalewski string instruments, Jerzy Nowakowski, Marian Knobloch and Zbigniew Gubernat.
     The band used unconventional sound and stage effects. The photos show the performers in white lab coats, which served to... heighten the strobe effect. Strobe lights came into use in discos many years later.
     The music archive holds eight of the band's radio recordings. Number eight is the song  Kiedy będę żałował, which for several weeks was number one in the chart of Polish Radio Programme III.
