Really grooving jazz-standard by Irving Berlin, written around 1927.
F (verse) / Fm (chorus)
In the intro, that strange sign (in German it is called a „Faulenzer“ - layabout) means to repeat the preceding bars. I love the tricky rhythm in the chorus, it took me some effort but after a while it flows naturally. The „putting on the ritz“ part is quite fast. Here I find it indeed more convenient to jump to the e on fifth fret / second string rather than play an open e-string. But, up to you as always.
When you (or your fingers) are tired of the repetitions, go from the „segno“ to the ending.
