Name that tune
A classic that can be played in many formats. You could read out some obscure lyrics from a song, facts about the song/ artist etc or, most popular, play the first 5 – 10 seconds (as long as the title isn't mentioned). The person playing then has to name the song within a certain time limit (10 -30 seconds is usually fine if there’s no conferring). It’s up to you if you want to add in additional rules such as allowing the intro to be played 3 times. You can also do it like a pub quiz where everyone has to write down their answers as you go through different rounds, or individually where each person/ team gets a song that they have to guess before you move on to the next. I'd also recommend a ‘mastermind' type round for the B2B. Let her choose a category that she's confident in, and then give her a whole round of intros in that category. If you need Category inspiration you could check out the following lists; 80’s, 90’s, 2000’s. Power Ballads, Christmas songs, Disney, From the Movies, Karaoke Classics and Guilty pleasures. Remember to try and cater to the whole room, as not everyone’s musical tastes will be the same. Here’s a little scoresheet to help you keep track.
*Bonus round. For laughs, take turns having one person from each team take a mouthful of water and try to hum their teammates a song to guess. Hilarity ensues when the rest of the room is laughing and said person ends up spitting water everywhere.
