Help with '70's song title

Hi. I heard a song on the Sirrius radio 70's station that I had not heard in years. I remember the song, but after all these years had forgotten it.

twice the course goes something like :

"you know I can't dance, you know i cant dance. You know I can't dance, you know I can't dance...I can't dance....I can't da-nce

The ending goes something like:

wait, I think I can dance I think I can dance

Then goes onto talking about all the dances he begins to do

Any help out there on title and artist?

Thank you for any help
