After I posted, 11th March 2003, I found another site, http://ourworld.compuserve.com/homepages/mamg/churches.htm#20, which says:
"St. Clement, Eastcheap - Wren
This is another small, intimate church, being only sixty-four feet long and forty feet wide, and is the third church to have been built on this site, the earliest church having been demolished in the 15th century, and the second was the first church to be destroyed by the Great Fire of London. Actually, it is not in Eastcheap as we know it now, but in St. Clement's Lane off King William Street, though this apparently was the old Eastcheap in days gone by. Its exterior is not impressive, as it is sandwiched between two office blocks, and, indeed, unless you are searching diligently for it, you can easily not notice a church is there.
The old nursery rhyme "Oranges and Lemons say the Bells of St. Clement's" originated here because the wharf where cargoes of citrus fruits were unloaded lay just the other side of King William Street when the Thames was a much wider river than it now is, and the church bells were reputed to ring a peal when a cargo arrived."

Incidently, the church of St Mary-le-Bow has a lovely winged dragon on its spire... Photograph at: http://www.hawkins.ndirect.co.uk/north_london_walkers/info_142.htm
