I hope you were playing "Fracture" and "Larks' Tongues in Aspic, Part 2"
No...that band was a rock band - Zep, ZZ, Purple, Sabbath, Rainbow - named after the Rainbow album. The tune Difficult to Cure is Blackmore's instrumental version of the choral from Beethoven's 9th symphony. We never did get a singer. :rsmile:
