The incident of having to marry the organist's daughter was Buxtehude
I believe.  It was also about 20 years prior to the opening in Leipzig.
Bach was already married as well as Telemann, in 1721.

I am not sure about the logic the Maestro Goebbel uses in terms of Telemann
being an aristocrat from Lutheran Clergy and the position in Leipzig would
had been a demotion for him.  Obviously Telemann wanted a church position.
He could had been appointed to any secular court that he wanted, he was
that popular.  Like Bach, he really wanted to express himself musically
in a church setting.  They both were very religious men.  Telemann had
written music for the New Church while as a student in Leipzig, and we
have an surviving Magnificat that dates from circa 1700 that was composed
specifically for performance in Leipzig.  Telemann had the same type of
position in Hamburg as the position was in Leipzig: a civic post for
teaching music to students and basically overseeing musical performances
in the city churches.

Thankfully more and more of Telemann's cantatas are seeing the light of
day.  CPO has been recording a good deal of the them in the last few years.

Again at the risk of repetition: Graupner's music is in dire need of
recording.  He was the 2nd choice for Leipzig after Telemann btw.
