Of the 4 selections, only "Don't" is not in my perpetual mental jukebox (sometimes the song will start playing on its own, occasionally with altered lyrics). "Volare" is in that category as well.

Twitty: 96.5 Hard to believe it didn't cross over to the Country chart.

Elvis: 95.5. More restraint and delicacy than his usual hits.

Everlys: 98. Amazing crossover phenomenon. I don't think the music industry knew how to promote them.

Edwards: 95

A similarly themed hit from 1964 (I don't know its chart status), Roy Orbison's "In Dreams"--certainly high on David Lynch's list.
