Hi Tonnie,

It was worth a try :-)

Side note 1.
When we see chords like Eb7#5 and look at them in context, they are quite often the result of the arrangement using voice leading which creates the alteration.
For example: the sequence in A Felicidade you are referencing in my chart is in bars 29-31 and has Bbm7 to Eb7 to Eb7#5 to Ab6 . A typical voice line would use the notes Ab (in the Bbm7) to Bb (in the Eb7) to B (in the Eb7#5) to C (in the Ab6.).

Side note 2.
You will do no harm to the arrangement by ignoring the Eb7#5 and keeping Eb7 for the entire bar.
