Classical Mullins

Rich Mullins was learning to play classical piano music while he was still in elementary school.  Richard's first big hit, Sing Your Praise to the Lord,  later recorded by Amy Grant, demonstrated his classical roots.  Amy left out the song's bridge, but in this performance at Wheaton College,  Richard leaves it in:
Richard could play both of the complete works heard below and many others, but he didn't perform them for the public because his greatest musical strength was improvisation, which led him to combine phrases from the two classical works below into his own song introduction, above.   You will find Richard's opening phrase at 1:38-1:47 Richard follows up with a few bars borrowed from Tchaikovsky's Piano Concerto #1.  You can hear it starting at 8:12-8:20
