First recorded (as a demo) by Jackson Browne & Glenn Frey (1972).
Hit version by The Eagles (US #12 1972).
Also recorded by Jackson Browne (1973).
From the wiki: “Jackson Browne originally began writing ‘Take It Easy’ in 1971 for his own eponymous debut album but was having difficulty finishing the song. His friend and then-neighbor Glenn Frey had heard an early version and later asked Browne about it. Browne then played the unfinished second verse that begins with ‘Well, I’m a-standin’ on a corner in Winslow, Arizona…’, and Frey finished the verse with ‘It’s a girl, my lord, in a flatbed Ford, slowin’ down to take a look at me.’ Browne was very happy with the result and suggested that they co-write the song.
