Mein Vater war ein Wandersmann

Song for summer!

Das Blaue Blume - The Blue Flower -- which appears at 1:15 -- is an element of  German tradition and stands for desire, love, and the metaphysical striving for the infinite sublime.

I love to go a-wandering
Along the mountain track 
And as I go, I love to sing
My knapsack on my back

Val-deri, val-dera
Val-deri, val-dera
Ha, ha, ha, ha, ha, ha
Ha
Val-dera
My knapsack on my back

I love to wander by the stream 
That dances in the sun
So joyously it calls to me
Come join my happy song

Val-eri, val-dera
Val-deri, val-dera
Ha, ha, ha, ha, ha, ha
Ha
Val-era
Come join my happy song

I wave my hat to all I meet
And they wave back to me
And blackbirds call so loud and sweet
From ev'ry green wood tree

Val-eri, val-dera
Val-deri, val-dera
Val-deri, val-dera

Oh, may I go a-wandering
Until the day I die
Oh, may I always laugh and sing
Beneath god's clear blue sky

Val-eri, val-dera
Val-eri, val-dera
Ha, ha, ha, ha, ha, ha
Ha
val-dera
Beneath the clear blue sky

Beneath the clear blue sky

From Wiki:

The Happy Wanderer" ("Der fröhliche Wanderer" or "Mein Vater war ein Wandersmann") is a popular song. The original text was written by Florenz Friedrich Sigismund (1788-1857).^[1][2] The present tune was composed by Friedrich-Wilhelm Möller shortly after World War II. The work is often mistaken for a German folk song, but it is actually an original composition. His sister Edith Möller conducted a small amateur children's and youth choir in Schaumburg County, Northern Germany, internationally named Obernkirchen Children's Choir, in Germany named Schaumburger Märchensänger.^[3] She adapted Sigismund's words for her choir.^[1]

In 1953, a BBC radio broadcast of the choir's winning performance at the Llangollen International Musical Eisteddfod turned the song into an instant hit. On January 22, 1954, the song entered the UK singles chart and stayed on the chart—only a Top 12 at the time—for 26 non-consecutive weeks, peaking at Number 2 (for five consecutive weeks).

With the BBC's strong international influence "The Happy Wanderer" turned up everywhere, e.g., as the winning song of the 1955 calypso road-march season of the Trinidad Carnival. People protested after this event and complained that only calypsos should be chosen over foreign music.

The amateur choir, many of whose original members were war orphans, turned into an unlikely international phenomenon in the following years. The group performed on many international tours under the name Obernkirchen Children's Choir and recorded several albums. They made two appearances on The Ed Sullivan Show (November 29, 1964, and December 11, 1966).
