I shouldn't have been surprised to find this. You could hear medleys once in a while in the 60's and 70's: The Letterman charted with "I Think I'm Going Out of My Head/Can't Take My Eyes Off of You," The Fifth Dimension with "Aquarius/Let The Sunshine In," and Glen Campbell with "Then You Can Tell Me Goodbye/Don't Pull Your Love." Oh yeah, and the Spinners medleyed twice. As for this one, it may not have gone very high on the charts, but it's better than some stuff out now.
This may have been one of Ms. Gore's last charted hits. I think this came out in 1969. I always have liked her a LOT, and still do even today! What a fine lady!
