The name of the site http://musiciansfriend.com always reminds me of another similar name: the old throat lozenge, Fisherman's Friend, which has apparently been around since 1865.
I've never personally seen it used by fishermen, although that was who it was first sold to, but my connection with it is in its use by singers, who, at one time swore by it as a cure for throats that weren't quite doing their job when it came to singing. Like a lot of things it seems to have had its day as far as singers are concerned - they've no doubt found something more soothing - but the actual Fisherman's Friend lozenge is still going strong, the company producing five billion of the things a year. That's enough to soothe the throats of around two-thirds of the world's population at any one time. Good grief.
The curious thing is that the Musician's Friend, as a name, would have been more appropriate for singers. When they soothed themselves with a Fisherman's Friend, you had to wonder at the compability.
