Their classic line-up included (apart from Kossela):  Krzysztof Klenczon- g, voc, Bernard Dornowski - g,voc, Seweryn Krajewski - bg, voc and Jerzy Skrzypczyk - dr, voc. The last two guys had to pick nicknamesbecause they were still musical high-school students at the time and so banned from playing in a "big-beat" combo. They did a lot of gigs at the seaside launching the slogan "We play and sing the loudest in Poland".
Their shows continued to draw thousands of young fans. The rising popularity enabled them to go into the studio to record in May for the radio and in the fall for their first EP (EPs were a standard record format at the time in Poland; 45's were much rarer than in the West). In late '66 they recorded their first lp "To wlasnie my" (released in '67). Their second album "2" was sold in record 260 000 copies and the band started to sweep the board in all kinds of rankings, charts andcompetitions.

  Their music was largely influenced by the British Invasion, especially the Beatles.  They persisted with that cheerful,psychedelia-uncontaminated sound until '69 even though it had been long outdated in the West. Although they didn't rock very hard, they were talented songwriters.  The result was they produced hit after hit and even if one doesn't like their poppy style, it should be admitted though they never did a cover! This is really exceptional'cause the bands that released 3 lps worth of material in the '60s without a cover could  be
counted on the fingers of one hand.
  However, in 1967 Kossela left and then in 1970 Klenczon  did to form Trzy Korony, a much tougher outfit. Krajewski took the lead but the band turned to mainstream folklore-tinged pop, perhaps not of interest to the
reader of this page. They disbanded around 1979. Now they are the best remembered 60's band in Poland.

Trivia: the band received a special mention from Billboard in 1969.
