"In a Dream"

"In a Dream" was a song the Seventh Doctor played on his gramophone while transporting the Master's remains to Gallifrey. When the Master broke free from his casket, the record playing the song started skipping, alerting the Doctor. The subsequent search for the Master resulted in the Doctor's regeneration. After the Master had been defeated, the Eighth Doctor began playing the song again, only for the record to start once again skipping. (TV: Doctor Who)
