Guy singing in the back, Tomas Ledin. Married to Stikkan Anderssons daughter Marie. Has his own carrier as a singer/song writer in Sweden, still preforming. His part of the "ABBA family", he does a duett with Agnetha called "Never again" back in 1982. You can look that one up.
The pop genre's best female ever: Annifrid Lyngstad ABBA. The pop genre´s second best female vibrato ever: Agnetha Fältskog, also ABBA. Not that I'm an expert, and also I'm a Swede and therefore biased. But still.
I like to see your reactions, that's why I would especially like it if you would react to the abba song My love, my life - Agnetha sings lead vocals (there is no live version, I suggest a video from the TV special Abba dabba doo , 1976) - you can easily find, that video is on my channel, right at the beginning.. Bjorn said about this song that Agnetha's soprano voice is the purest in it So, please, please..
As a tenor you really should listen to Dimash Kudaibergen from Kazakhstan. He's the best singer in the world and this century right now. No male or female can match his voice. Not even Mariah Carey can match his voice. He has a vocal range of 7.7 and whistle tone up to D8 the dog whistle sound. I highly recommend you start with SOS 2021 Digital show during the pandemic. He has a huge rabbit hole to dive into and a huge fan base called Dears. 👍 🇳🇴
