Input: Consider Input: Question: Which band who are one of the few who have 50 years in music formed first? Passage:In 2010, the Scorpions announced their farewell tour. Before they retire, they wanted to release a bonus track album from leftovers from seventies and eighties just for the fans. After playing the final show in Munich in December, 2012, band planned to take a break and go on vacation. In January, 2013, MTV contacted the band and asked if they are interested in doing the MTV Unplugged album. They agreed on doing that project and turned out to be successful. That whole thing pushed back the bonus track project. As soon as they have finished the MTV Unplugged project, band immediately went back to studio to work on bonus track project. Band was listening the recordings they have already prepared for the project. They were happy with the result and Rudolf Schenker said that he has a tape with some songs that they could also use for this project. While searching for the tape, Schenker found an old ledger in which his mother enumerated the loans that his father provided to him, so he could buy all the equipment and establish the band. He looked into the book and it said: "September, 1965". He went back to the studio and told the band what he found and their manager said that it would be great idea to celebrate 50th Anniversary since they are the only German band who is 50 years in music and one of the few in the world along with The Rolling Stones, The Who, Beach Boys and Pink Floyd. Manager suggested to the band that they contact the promoters and see if they are interested in band doing the 50th Anniversary Tour. Then Schenker suggested that if band is going to do a 50th Anniversary Tour, then band needs to release brand new studio album. So the band went again into the listening process of bonus track material that they have already prepare and see if they can improve something, like choruses and riffs. After that, they re-recorded the old stuff and started to write new songs with the producers Mikael Nord Andersson and Martin Hansen. The result was the album Return to Forever.
