UPDATE: A petition has been launched by Cardiff PSC in Wales, asking Tom Jones to cancel his gig , see https://www.change.org/en-GB/petitions/sir-tom-jones-please-don-t-play-in-apartheid-israel-2
Why would a Tom Jones concert ever be considered a strong political act?
Answer: It would if he plays in Israel. It would be broadcast by the Israeli regime that he personally supports Israel, as has been done with previous artists who have breached the boycott.
The Israeli press has already aggressively appropriated his artistic talent, using him to normalize apartheid. Here are some of the many examples found online:

With the boycott of Israel growing by musicians who are anti-apartheid, it becomes hard for Israel to lure artists. Tom Jones may not be aware of the boycott but soon he will be, as a concerted human rights campaign (see https://www.facebook.com/Tom.Jones.NotUnusual.Boycott.Apartheid) is calling on him to cancel his concert.
