Isn't just about any song good live, if you like the band? Saw the Clash play all of the above songs live and just about came out of my skin. Hell, I'd probably even jump around and pump my fist to Blue Heaven if I was there at the show.
And point taken on RTC. I remember from an interview with Joe and Topper, hearing about how Topper was essentially fooling around between songs while recording Sandanista, and pieced together much of the song. I think the rest of the band just kinda looked at him in amazement and then said, alright lets record it.
