Wish You Were Here was written by Pink Floyd and released on an album of that name in 1975. It is song about loss (Syd Barrett, a band member) and disillusionment with the music industry.   Over the years it has been sung by Pink Floyd, Roger Waters, and David Gilmour in their concerts and it has been included in the greatest hits compilations.   I heard it performed live twice.   Pink Floyd remains a long-term favorite and there are many other of their songs on my playlists.
