I had a quick look at the Mudcat midi site the other day, and some midis seem to have snuck in for missing tunes. Have they been there for ever, and did they just appear recently without anybody noticing? Here are the results of a quick trawl, but I'm sure there could be others.

561 CAMBOURNE HILL

678 COLIN AND PHOEBE - couldn't download the midi to check.

845 DESERTER - there are two midis called The Deserter From Kent. They both fit the words given in DT. The song says he came from the west of Kent, and later that he was taken to "Maystone Jail". Maidstone is the county town of Kent, and still has a prison, I believe. So is this a match or not?

885 AN DO/RD FIANNA:, - midi is called O/ro/ se/ do bheatha 'bhaile

1257 GAMBLER, 1258 THE GAMBLER (2), 1259 THE GAMBLER (3), - couldn't download the midi to check which (if any) of these three it fits.

1321 GLENCOE - midi is titled Rape of Glencoe

1774 IN THE OLD BAZAAR IN CAIRO - a full length, multi-track version

2507 NOBLEMAN'S WEDDING

2514 THE NORTHERN LIGHTS OF OLD ABERDEEN - the tune has a 4-line chorus, the DT text has three. I think the third line is missing from DT.

2537 O'REILLY AND THE BIG MCNEILL

2599 THE OLD FISH SONG

3024 ROW-DOW-DOW

3240 THE SOUTH COAST

3269 A STOR MO CHROI

3699 WHEN FATHER PAPERED THE PARLOUR - chorus only

Wassail! V
