This is my fourth of five feel-good songs:
It's "Together in Electric Dreams" by Philip Oakey & Giorgio Moroder. The song was originally released in 1984 and is from both the album Philip Oakey & Giorgio Moroder and the soundtrack to the film Electric Dreams, for which the song was recorded. The song went on to become a greater success than the actual film; in fact, even I wasn't aware of the film's existence until conducting a little research for this post.
The version of "Together in Electric Dreams" I'm most familar with is the 12" one, as it was in Dad's record collection.
