S.T.S. (STS) piano sheet music of popular songs

S.T.S. (also STS; acronym for "Steinbäcker – Timischl – Schiffkowitz") was a three-member Austropop band from Graz in Austria. Its most famous songs are "Großvater", "Irgendwann bleib i dann dort", "Gö, du bleibst heut Nacht bei mir" and "Fürstenfeld". The trio was founded in 1978 by Gert Steinbäcker, Günter Timischl and Schiffkowitz (real name Helmut Röhrling). All three members are from Styria, a fact that repeatedly referenced in the group's songs. The three musicians played acoustic guitar and sang the chorus of their songs in three-part harmony whereas the solo part was sung by the composer with a few exceptions. Instrumentation and vocals reveal influences of bands such as Crosby, Stills and Nash.
