It would never work as an opener because it barely works as any part of the set-list in general.
Micks falsetto ain't what it used to be.
Listen to any recent live performances of this song, and you almost cringe when Mick yelps out "Baby"!!!
I used to love this song as part of Tattoo You, but the recent live versions have tainted my enthusiasm.
Same goes with Can't You Hear Me Knocking. I refuse to listen to any Ronnie version.
