Shortly after Xinna and I moved to London from Beijing in June 2003, Mike came to stay with us at York Terrace East - we had a great time exploring London, visiting the café opposite 221b Baker Street, wandering around streets great and small.  It was a fun few days, we discovered the McLaren showroom in Mayfair which had their latest supercar on show much to Mike's delight - 'no way!'... A lovely memory for which I thank God. 
(I can't remember exactly when it was but between June 2003 and August 2004 because we moved to Brockley in 2004.
