Hi,
Back in 1993 I heard a song, sung by a guy, with the lyric 'even in the darkest night, I can find a little sunshine'. Anyone out there know who could have sung this. Any help greatly appreciated.

It isn't Roger Miller is it? I googled it but couldn't find the lyrics word for word the way you had it.

The several versions of "You've Got A Friend," have similar lyrics, too.
They say "To brighten up even your darkest night" in the first stanza.
