I was gonna write "Happy Birthday" whilst excluding all the vowels just because for no reason, but reneged upon the whole affair whence I couldn't figure out if I shoulda nixed the "y"s as well.
I would assume yes, given the pronunciation of those words- but I decided to consult the almighty Google for a more official stance upon the matter.

The letter Y is inherently vacillating in its nature and usage, and consequently is sometimes a vowel, sometimes a consonant, depending upon how it is used in the name.
When determining if the Y is a vowel or a consonant, the basic rule is this:
When the letter serves as a vowel, and in fact sounds like one, it is a vowel. The same is true when the Y serves as the only vowel in the syllable. Examples of both of these cases are such names as Lynn, Yvonne, Mary, Betty, Elly, and Bryan.
However, if the Y does not provide a separate vowel sound, as when it is coupled with another vowel, it is considered a consonant.
In names such as Maloney or Murray, the Y is a consonant, because the vowel sound depends upon the long E in Maloney and the long A in Murray.
In general, the Y is a consonant when the syllable already has a vowel. Also, the Y is considered a consonant when it is used in place of the soft J sound, such as in the name Yolanda or Yoda.
In the names Bryan and Wyatt, the Y is a vowel, because it provides the only vowel sound for the first syllable of both names. For both of these names, the letter A is part of the second syllable, and therefore does not influence the nature of the Y.
My doubts put to rest, there you have it.
Hpp Brthdy!
