1958 had three songs worth mentioning.
first is of course Italy: Domenico Modugno - Nel Blu Dipinto Di Blu (Volare), the first eurovision song that is still being played around. and it's not bad, perhaps best of this year. https://y.com.sb/watch?v=9DPAb9-Stmo&list=PLD42A1900DFFBDFA1&index=0
Denmark: Raquel Rastenni - Jeg Rev Et Blad Ud Af Min Dagbog. looks like i have a soft spot for songs in danish. https://y.com.sb/watch?v=IGMLrLgVmR0&list=PLD42A1900DFFBDFA1&index=5
Switzerland: Lys Assia - Giorgio, early example of ESC nonsens https://y.com.sb/watch?v=gGsalvX8K4c&list=PLD42A1900DFFBDFA1&index=9
