For my favourite ukulele tunes, some that I like are:
Love Her Madly – The Doors – Great rhythm to this song but with a tricky section
Can’t Get You Out Of My Head – Kylie Minogue – good chord changes
Dream A Little Dream – Mamas & Papas
I Will Survive – Gloria Gaynor
The Locomotion – Little Eva
Please Don’t Let Me Be Misunderstood – The Animals
Venus – Shocking Blue
The Man Who Sold The World – David Bowie
She’s Not There – The Zombies
In the classics I enjoy:
I Got A Woman – Ray Charles
Blueberry Hill – Fats Domino
Fly Me To The Moon – Frank Sinatra etc
Music To Watch Girls By – Andy Williams
Summertime – Porgy & Bess
Close To You - Carpenters
My Baby Just Cares For Me – Nina Simone
Another I like is Rasputin - Boney M.
I also have Wooden Heart in D with the melody notes, which I think works better than in G.
Most have clever chord changes & a good tune.
I‘ll stop there but I have more. They’re all nicked from over the interweb – if you’d like any of these please let me know on club nights.
I have watched quite a lot on YouTube & most things by Sophie Madeline are really good, in particular is Wolf, a song originally by First Aid Kit, but it’s not really a strummer as such. But I did find a good one-man band version of Love Her Madly by logophile.
