Without too much over-thinking, head-scratching and deep-diving, could you please comment with any three songs you like / play that :
use beginner-ish chords
are suitable for beginners and up
are popular in social settings
are often played in guitar clubs or open mics
EDIT - If you are new to this topic please do not read the other suggestions before posting your own. I want you to come at this without having seen any other replies.
There’s this dude on the internet that has a playlist of lessons of songs to play in social settings and has a beginner friendly one too.
If I were to name three songs… hmmm… Maybe Brown Eyed Girl, American Pie and Knocking on Heaven’s Door. But I guess Wonderwall will be popular with the upcoming gigs.
Obviously, here where I live in social settings people love to sing Polish songs and I played tons of them. However in a club/pub environment various English language songs are quite popular, too. I’ll give you some examples of songs I played and sang, where the audience would often join me at least in the chorus:
Merle Travis: “16 Tons” (we have Polish lyrics for this song, too);
ELP: “Lucky Man” (a beautiful song with really easy chords even for a beginner);
“Whiskey In The Jar” (English and Polish lyrics were usually sung);
Eric Clapton “Wonderful Tonight” (sounds great even played on an acoustic, easy chords).
