Shocking Blue was joined by Tee Set and George Baker Selection as successful acts that producer Jerry Ross brought to the U.S. Ross, a lyricist traveled to Hamburg and Zurich in 1969. He discovered that tracks by the Dutch bands were available. Shocking Blue's Venus became a mega hit in the United States. Released in December 1969 it peaked at #1 in February 1970. Tee Set's "Ma Belle Amie" was a big hit in America as well, along with "Little Green Bag" by George Baker. The mini Dutch invasion recalled the previous, albeit larger, English invasion, of the mid 1960s.
