I remember the "Marching behind William Tell" musical beeswax and then my math skills fail me... Perhaps the music had been changed for syndication and the music included here is the original, or perhaps not..."The Adventures of William Tell" includes thirty-nine episodes: l The Emperor's hat, 2 The Hostages, 3 The Secret Death, 4 The Gauntlet of St. Gerhardt, 5 The Prisoner, 6 Voice In the Night, 7 The Rats Who Died, 8 The Baroness, 9 The Elixer, 10 The Suspect, 11 The Cuckoo,12 The Bear, 13 The Magic Powder, 14 The Golden Wheel, 15 The Bride, 16 The Boy Slaves, 17 The Young Widow, 18 Landslide, 19 The Trap, 20 The Shrew, 21 The Manhunt, 22 The Killer, 23 The Surgeon, 25 The Ensign, 26 The Avenger, 27 The Bandit, 28 Gessler's Daughter, 29 The General's Daughter, 30 The Raid, 31 Castle of Fear, 32 The Black Brothers, 33 The Lost Letter, 34 The Secret Weapon, 35 The Master Spy, 36 The Traitor, 37 The Spider, 38 The Mountain People, 39 Undercover. This DVD collection of three DVDs includes ten episodes each in no particular order. And, that's the way it goes... However, reproduction is more than adequate. This is just a boy action television program. Oh well, so much the better. Perhaps, someday all thirty-nine episodes will be sold together with the marching song. Until then, buy this edition.
