Music Banter - Help me find this song.

Don't have much to go on here, but hopefully some of you music lovers can help.

The song is a classic, 70's pop song. Similar style to 'I Want you Back' by the Jackson 5, or 'September - Earth Wind & Fire'. Feel good 70's music.

I am PRETTY sure it featured a female lead vocalist. I heard it in the grocery store and knew the song, but cannot for the life of me remember the lyrics, nor could I hum a tune right now.

Thanks!
