I Can't Quit You Baby - 23/3/69 Top Gear;Remaster

Many musician types consider this one of Led Zeppelin's technically strongest performances, but Jimmy Page admits that it's far from perfect. He told Guitar Player magazine in 1977: "There are mistakes in it, but it doesn't make any difference. I'll always leave the mistakes in. I can't help it. The timing bits on the A and Bb parts are right, though it might sound wrong. The timing just sounds off. But there are some wrong notes. You've got to be reasonably honest about it."

This is based on a Blues song by Willie Dixon that he wrote for Otis Rush, who recorded it in 1956. Many of Led Zeppelin's songs were influenced by old blues or folk songs.

The version on Coda is a soundcheck for a show at Royal Albert Hall on January 9, 1970. Coda is a collection of outtakes released after John Bonham died.
