Someday out of the blue is a song in the show. It is performed by Elton John and it appears in the episode Cronarella as part of the soundtrack.
Some day out of the blue In a crowded street or a deserted square I'll turn and I'll see you as if our love were new Some day we can start again, some day soon
Here comes the night Here come the memories Lost in your arms Down in the foreign fields
Not so long ago Seems like eternity Those sweet afternoons Still capture me
I still believe I still put faith in us We had it all and watched it slip away Where are we now?
Not where we want to be Those hot afternoons Still follow me
Some day out of the blue Maybe years from now Or tomorrow night I'll turn and I'll see you
As if we always knew Some day we would live again, some day soon
I still believe I still put faith in us
