The video is from a concert in Freiburg (Germany) in 1987.
Go to 5:34 for the McLaughlin solo (can’t get timestamp to work for this). The song is “Spain” by Chick Corea. Apperently, he injured one of his fretting hand fingers, and starts the solo by removing the bandage and then goes on to light speed shreding. Enjoy ! BTW. the whole concert is worth a listen if you have the time
