Three LP's of LH518 "Senior" have been commercially available:
these were re-released several times, with different covers.
All recordings of this organ were made in the workshop of Romain
Charles Hooghuys in Zeebrugge; also, all arrangements (except
one) are from his hand. Typical for all arrangements is the frequent
(ab)use of the ability of the organ to repeat notes very quickly.
On the covers, there's often a different city name on the organ
than "Grammont": whenever Romain Charles went to play with the
organ, he had the habit of placing a wooden plate on the organ
with the name of the city where he was playing.
Some titles or composers' names are misspelled or simply incorrect
on the covers; below are given the correct details.
