A few tickets became available again from the official vendor for the concert in Rio, in case anyone is interested:

Rio de Janeiro 16.12.2023

A rumour regarding Brazilian tour dates:

Got Back

30.11: Brasília
03.12: Belo Horizonte
07.12: São Paulo
10.12: São Paulo
13.12: Curitiba
16.12: Rio de Janeiro

However, another source has claimed that the concert in Rio will happen before the concert in Curitiba.

Latest rumor: Paul will say goodbye to Brazil in December, at the Maracanã Stadium, where he did those record-breaking concerts in April 1990.

@wandy Yes, I have been to a few McCartney concerts in South American countries during the 2010s in which a support band played a few songs before everything else (DJ, video montage, Paul).

New rumour of negotiations for a concert in Brazil later this year:

Arena MRV, Belo Horizonte, Brazil, 2023?

This time they're talking about Belo Horizonte, the city of the opening night of the Out There tour back in 2013, which also received a concert in 2017 during the One On One tour.

"Rumour has it that Paul McCartney is about to announce some European concert dates"

"Seems around 13 dates in Germany, Austria and Switzerland and one in London according to this rumour"

2023 European Tour?

@thenightfish I suppose April is still possible. I think they used to sell tickets about 3 months in advance (sometimes less than that) but that was pre-covid. I don't know whether things are different now.

Another rumour that has been going around for a few days but has not been discussed here yet:

https://calicoskiesradio.blogspot.com/2022/12/mccartney-2023-otro-dato-sudamericano.html

Estadio River Plate, Buenos Aires, Argentina, April 2023.

This rumour has been going around for a few days, but since it hasn't been shared here yet:

Paul in Santiago, Chile, April 2023?

Updated rumor regarding Paul's return to Brazil: February 1st, 2023 at Morumbi stadium in Sao Paulo.

A few months ago there was a short article about it, mentioning that there were negotiations for 3 concerts in that stadium next February.

I still think it's a little unlikely, but you never know.
