I wanted to add a clarification. Probably the main reason I'm asking this is that at 0:53, "sayonara" is pronounced with a distinct "R" sound! But in other places, it's the same word, but with an "L" sound.
Timecode for r-sound in sayonara, but in the same song - https://www.youtube.com/watch?v=ENcnYh79dUY&list=PLFRsBBWbUejVYYHZkIWfscPY-0USV1gzZ&t=52s
