Disco song rehearsal and class perfomance

The disco song was musically more challenging than the psychedelic one.
The tempo was faster, there were more chords, more words, more changes and a totally different mood than the other song, therefore, it became a challenge.
Playing according the time of the backing track was a lot harder this time and we lose the tempo often. For Natalie this was worse because she had to play the chords in the keyboard really fast, so she practised a lot.
I had to learn the lyrics what I did not thought was complicated until I realized that there were a lot of words in each verse sang fast and that had no story lead for me to hold on, so I ended up learning by repetition.
The last but not least thing we had to worry about was the performance.As it was a song about dancing and having fun, we should not stay petrified, but with all the things we had to sort out first, there was not going to be a performance already.
