To promote this year's Hamburg Master Series event, Becker has organised exhibition matches on a Davis Cup format featuring himself, Stich and the McEnroe brothers, John and Patrick (instead of Krickstein).
You can see "the oldies" with live photos and actual results (momentarily: Stich : Patrick McEnroe first set 7:6) here

Do you remember that in 1987 Becker defeated John McEnroe in 6 hours, 20 minutes in Davis Cup, two minutes shy of the longest match in the Open Era (between McEnroe and Wilander)?
