Hrm. No.11 in a set, no.14 is his Fantasia op.93 on St. Ann's Tune which may be dateable and which in turn may help date the March. Perhaps this should be considered not as a separate work but as a set of 15-odd (just as another organ march by Silas is reviewed in an 1879 Musical Times as part of a group of 6 works by him for the instrument in which it is published- the description makes it clear it is a different one, with a first trio in minor, unlike this one) Eric 12:53, 21 January 2012 (UTC)
