I learned this piece 50 years ago, at the age of 16 or 17, not as well as Manuel, but not bad as I recall. Wonderful triple tonguing in the last variation! I never had what it takes to go pro though hearing it today brings back some wonderful memories.
I am about to record this on a cornet, will be interesting to hear the comparison. Your tempi are very similar to my own. I doubt I shall make as good a job as this!
