Manfred Retzlaff translated "Ho Jesu', amiko mia" according to both the English original by Joseph M. Scriven (1857) and the German translation by Ernst Gebhardt (1832-1899). A message from Reinhard Pflueger on the KELI-Dia Regno email list states that Manfred Retzlaff also translated the fourth stanza, but I do not have that.
