I'm not sure why, but I've had several people PM me about MP3s of "I'm So Afraid" on the Japanese leg of the 1977 tour.

The question may have stemmed from a request to get an MP3 of the performance of the song on the Young Music TV show that we all have. There seems to be some confusion as to whether "So Afraid" is there in its entirety. It's been a long time since I've looked at a tape of the show, but I don't remember any of the songs being shortened -- only that numerous songs from the set weren't included in the TV show to begin with.
