Apart from the example posted? If you look at the sort of hymns common in the US and written in the short-note style favoured there, then anything that starts with three quavers. Flicking through, I see "O Waly Waly" which is easy to spot because it has a 3/4 signature. OTOH I see "The Voice of Jesus" (not a hymn I know) which has no time signature (mixed 3/4 2/4) so the beaming is the _only_ indication of crochet rhythm. Even the lyrics (underlain, again a US convention) don't help. The two verses start: 1 The voice of ... 2 Chil-dren and ... which contradict each other (no surprise for 1993). These are typeset correctly, though whether you can call this hymn book properly typeset is debatable. Some of the word underlays are appallingly positioned. Then again, these ambiguities are not helped (or hindered) with UK hymn conventions: no time signatures, and longer note values where these anacruses are therefore notated in crochets. But better not to be told than to be told wrongly. > In “West Side Story”, the half-measure beams in “America” indicate where the > measure grooves in 6/8, and the full-measure beams indicate where the measure > grooves in 3/4.

I only have access to the choral selection by William Stickles, and the beaming there is excellent: two groups of three in the first bar, three groups of two in the second, and so on. The only bars with single beams are those like e8[ r e r e] r and r8 e[ r e r e] Similarly, in "I Feel Pretty" we have plenty of r4 f8[ f f f] | f4 But—and here's my point—that beaming is only in the piano part, not the voices. Beaming IFP that way would send the wrong message to the singers. The style needs to fit the both piece and the part.
