An overlooked cover tune XLIX

After hearing Richie Havens perform it at Woodstock, I'm surprised I've never heard any version of Gordon Lightfoot's "I Can't Make It Anymore" on the radio.  Havens gave Lightfoot's strong, relatable lyrics about not wanting to be in a relationship with someone any longer compelling life.  Although the faster studio version Havens recorded with strings is fine, the slower, starker version of it he sang at Woodstock is even more captivating.  I'm puzzled that I've never heard it on any noncommercial station.
