It's an obscure Bo Diddley song, that the Stones made famous.
It's often credited as Ellas McDaniel song, but that's Bo's real name.
You can find the Stones version in "Got Live If You Want "
"Nanker/ Phelge" was a psdeneom used by the Rolling Stones when they weren't sure who wrote the orginal song.
The Stones version is a killer.
"I'm Alright" (Ellas McDaniel) – 2:22
* Later released on the US version of Out of Our Heads album and on the US only album Got Live If You Want It!, the latter having different vocals.
Iggy has often credited "Out Of Our Heads" as his all time favourite Stones album. (I Cant Get No Satisfaction) is on the album, too...http://en.wikipedia.org/wiki/Got_LIVE_if_you_want_it!
