Question 4

这个答案有点复杂。历史断言是基于维基百科。我有 不是 已核实原始资料。因此，历史声明按原样提供，不保证或保证真实性。如果需要更正历史记录，请发表评论。

买者自负 ...

问题中发布的颂歌版本是 19 世纪的美国化版本。因此，它毫不奇怪地遭到了清教徒对酒精的怀疑。因此，原版中所有关于欢乐液体的提及均被删除。

我很不情愿地将这个混合版本包含在下面的文档中，但我建议颂歌者从更早的、不那么痛苦抑制的版本中寻找音乐灵感。

美国版本是托马斯·奥利芬特 15 年前提供的文字的清教版本。除了取消欢乐的饮料外，一个大厅显然对大西洋彼岸的人们来说也不够，所以他们从 1892 年开始更改了名称，并增加了要装饰的房间数量。

Oliphant 的文字是 1862 年的英国英语版本，与 Talhaiarn 的文字一起出版诺斯加兰，威尔士颂歌的原版。爱德华·琼斯的早期版本于 1794 年出版，但诺斯加兰年纪大了。

让事情更加复杂的是，这Fa la la ...句话原来是威尔士人重复的一句歌词的变形版Fal lal lal ...。谁知道会发生什么呢？那是……的混乱。此外，威尔士语版本用器乐叠句代替了第三个Fal lal lal ...，显然必须再次以不同的方式呈现。

现在诺斯加兰与圣诞节毫无关系。这是威尔士的一个更古老的传统，至少在东南部，它与 Y Fari Lwyd（灰色母马）有关。这包括在 Nos Galan（新年前夕）来回竞争地唱诗。一组人走在街上，抬着一个装饰好的母马的头骨，头骨固定在一根杆子上，并固定好，以便下巴可以张开和闭合。这组人在门口唱歌以示进入，里面的人通过关闭的门用歌声回答。如果该组在比赛中获胜，门就会打开，流浪者们会得到饮料。当然，到现在为止，这已经是仪式化了，各组之间来回唱着标准的诗句，流浪者唱完最后一首诗以确保胜利。

不用说，门通常是酒吧的门。因此，即使英式英语版本已经将其含义改得面目全非，美式英语版本中去掉酒精一词也几乎不能被视为偶然。也就是说，1862 年的英语单词绝不是与之并列的威尔士语单词的翻译。相反，它们是旨在与同一种音乐一起演唱的英语单词，这种音乐比威尔士语和英语诗歌都更古老。

恐怕所有这些都需要对 MWE 进行一些修改。但是，原始 MWE 仍会产生输出。只是不太有趣。此外，MWE 包含虚假空格，我在下面的屏幕截图中已将其删除，但在左侧创建了一个白色边距。这是因为行尾未正确注释。

请注意，与所有好的类一样，happyholidays当用户尝试使用已弃用的命令时，会发出警告。在这种情况下，\caroltitle{}没有影响（可能除了虚假间距），并且该类会告诉您如何相应地更新代码。

这是没有虚假空格并使用该类的当前版本的替代 MWE happyholidays。

请注意，上述 MWE 将不是如果类中的字体包或默认输出编码发生更改，则编译。如果字符由字母和单独的重音组成，而不是使用预组合的字形，则代码无法容忍在此上下文中使用威尔士重音字符之一。据我所知，berenis是标准发行版中唯一使用 pdfTeX 预组合字形的字体包。但是，如果使用 LuaTeX 或 XeTeX（未经测试）进行编译，它可能适用于其他字体。
