What song, or songs, were so well performed live that you almost don’t even want to listen to the studio version?

Here are some that come to mind for me:

Peter Gabriel – Don’t Give Up (on Secret World Live)
Simon and Garfunkel – For Emily, Whenever I May Find Her (on Simon and Garfunkel’s Greatest Hits
Simon and Garfunkel – Kathy’s Song (on Simon and Garfunkel’s Greatest Hits)
Journey – Stay Awhile (on Captured)
