"Ocean Deep" is a sentimental ballad written by Rod Trott and Jon Sweet and originally released in 1983 by British singer Cliff Richard on his album Silver.

Although pressure was mounted from fans and disc-jockeys, it was only after "Baby You're Dynamite" had finished its chart run that the record company finally flipped the single, promoting "Ocean Deep" to the A-side.

Richard discussed how he came to record the song with an interviewer from the Philippines, “Ocean Deep was an unusual one because it came through the post from two writers who I didn’t know; they were amateurs.
