It usually takes work to write a hit song. But now and then a performer creates one spontaneously.  Just ask Keith Richards about the song “Satisfaction”  During their tour of North America in 1965, the Rolling Stones spent a night in a Clearwater, Florida, motel. In the middle of the night, Keith Richards woke up with music in his head. He recorded it and played it to Mick and said the words that go with it are “I can’t get no satisfaction.” Jagger wrote the lyrics as he sat by the swimming pool. The song was actually recorded over Richard’s objections. It became the bands’ unofficial anthem, and the #1 song of 1965. After the death of Mick Jagger’s girlfriend, the world tour will commence at the end of May. The band will kick off at the Telenor Arena in Oslo, Norway on May 26 before playing 13 other dates around Europe and in Jerusalem.
