Need identifying early 80s song

[xsork]

I think the title of the song is :today is your lucky day. I Thought it was Harold Melvin & the blue notes, it isn't.

Does anyone know this disco song?

Harold Melvin and the Bluenotes..did do a cover of Today's your lucky day..which was one my favorites for 1984. This was a big hit on Kiss FM nyc...
