Rolling Stones Fans- I Need advice


I keep hearing the Stones Can't you hear me knocking? from Sticky Fingers and I would like to add it to my collection.
Where is the best copy of this cut. Is it vinyl or cd. Original or one of the 27 reissues?

Sadly, Mick Taylor's spring tour has been canceled due to illness. They're saying maybe in August now. Reports I read indicate Taylor was hospitalized with pneumonia.

Here's wishing Mr. Taylor a speedy recovery!
New remastered CD from 2009 is quite nice. I also like It's Only Rock and Roll, remastered in 2009 as well. Exile comes out this month with 10 new songs.
