The Doctor Who theme was composed by Ron Grainer and first realised electronically in 1963, becoming one of television's most recognisable title tunes. Peter Howell reworked it for 1980, giving the series a more modern synthesiser sound for its early eighties run until 1985. That version accompanied the closing era of Tom Baker and the tenure of Peter Davison, which helped fix it in fan memory. It remains widely shared by fans, collectors and editors who associate its sound with classic era repeats, conventions and anniversary retrospectives.
