Place it at the entrance or reveal in a birthday edit, then follow it with an air horn once the birthday person is on screen. Keep it as the centrepiece of the opening, and save a funny laugh for the reaction shot that comes after it ends.
About this sound
This is Marilyn Monroe's breathy, slow rendition of Happy Birthday, sung as 'Happy Birthday, Mr. President' in a soft, sultry voice that stretches every line. It feels playful, flirtatious and a little cheeky, turning a familiar birthday song into a starry, show-stopping moment. It comes from Monroe's famous performance for the President.
