María Mendiola, one half of the band Baccara best known for their disco anthem Yes Sir, I Can Boogie, has died at the age of 69.
The Spanish singer performed alongside bandmate Mayte Mateos, whose 1977 hit became the unofficial anthem of Scotland football fans.
After the Spanish duo split, Mendiola went on to perform with other artists initially under the name New Baccara, before reverting back to just Baccara.
Mendiola's management company, Tony Denton Promotions, confirmed the news of the singer's death but did not give further information about the circumstances around it.
Cristina Sevilla, who replaced Mendiola in Baccara after she stepped aside due to arthritis in 2008, announced the news of her passing in an Instagram post.
She wrote in Spanish: "How difficult it is to post this... My dear María, a wonderful artist, but above all my friend, has left us today.
"I have no words... I can only be thankful for how much love I have received from her and tell her what I got the opportunity to tell her so many times in life... I love you."
Yes Sir, I Can Boogie was first linked to Scottish football in 2015, when a video of Aberdeen and international defender Andy Considine signing the song in drag with others during his stag do, was leaked on YouTube.
The hit track reached number three in one UK singles chart in mid-November 2020 when Scotland defeated Serbia in a Euro 2020 play-off.
Footage of Considine and his team-mates dancing and singing along to the track went following the hit went viral.
The song, which has since been covered by Goldfrapp, The Fratellis and Sophie Ellis-Bextor, was heard being sung loudly and proudly by Scotland fans throughout the tournament in 2021.
