Britain's Eurovision contestant, Sam Ryder, visited British BBC Radio this week and performed a cover of Abbas' winning Eurovision entry Waterloo.
Ahead of the final night, Abbas' twitter account has retweeted the clip where Sam Ryder sings with the text "We love this - good luck tonight, Sam Ryder".
The group has also sent a thank you to the British newspaper Independent which ranked Waterloo as the best Eurovision winning song ever.
Swedish Cornelia Jakobs has not received a greeting.
