There is definitely a composer named John Travers. He was an early/mid 18th C English composer, mainly of organ music. Such things can easily be found by "googling". I tried Amazon/classical for the piece referred to, but couldn't find it listed as such. Maybe the actual title of the hymn is slightly different. There are several 18th C English hymnal CDs listed on Amazon. Suggest you have a fish around in there. If not try "google" search and try other sources.
