For perspective here is a wikipedia list of performers who died during a performance. The list probably includes only well known performers and wouldn't likely include teens that are part of a choir. I don't now whether the teens death was covid related or vaccine related or unrelated, just that people of all ages sometimes die unexpectedly.

There’s plenty of heart attacks in there. I’m not going to pick and choose line items of an excerpt. So quit frogjerking.
After looking at your list and investigating the deaths in more depth this list cannot be used as some sort of evidence that SADS is some sort of common occurrence.
A few were killed by a tsunami caused by a volcano, someone fell off a stage, another was bitten by a cobra, heart attacks caused by advanced cardiovascular disease, etc...
Also, it seems the ages of these people are way older than the teenager in the story. For example you listed the following which doesn't fit the circumstance of the article:
Nepali actor Bishnu Bhakta Phuyal died while acting on stage. He fainted during a performance at the theater in Kathmandu. - he was 79 yrs old and died of a brain hemorage.
Guitarist and jam band performer Colonel Bruce Hampton collapsed and died of a heart attack during a jam at an all-star concert held in honor of his 70th birthday
French barefoot singer Barbara Weldens collapsed while performing in a church in Gourdon, France, apparently from electrocution from a faulty cable on the floor.
17 September: Laudir de Oliveira, Brazilian percussionist and former member of the band Chicago, died of a heart attack during a performance in Rio de Janeiro, Brazil. - He was 77 years old
Kathakali dancer Madavoor Vasudevan Nair slumped on stage and died during a performance. He was 89 years old
Original Boston drummer Sib Hashian died after collapsing during a performance on the Legends of Rock cruise. He was 67 years old and was diagnosed with Kidney cancer as well.
Comedian Ian Cognito died of a heart attack during a show in Bicester. Reports indicate that he had been taking medication for a heart condition, and passed away from a heart attack. Was also a hard drinker as reported by the UK Sun. He was 60 yrs old
Juliano Cezar, Brazilian sertanejo singer, died of a heart attack during a concert in Uniflor, Paraná. He was 59 years old
Atlanta Symphony Orchestra Principal Bass Emeritus Jane Little collapsed and died on stage during the last 30 seconds of the orchestra's final encore of "There's No Business Like Show Business". She'd been undergoing chemotherapy for multiple myeloma and she was 89 years old
The more and more I go thru your list I don't even have to look hard to find out that it is quite a small minority (maybe none at all) of the people you list are even comparable at all to the 17 yr old that died suddenly. Did you take a look at the info that you posted at all?
are they the ages of the persons at the end of your excerpts?
if so, they are not young.
the sudden, unexplained deaths being reported of late are mostly under 50 years of age, well under 50 in most cases.
