Abba is highly logical.
Rondo is ABA, ABACA or ABACABA.
“Abacab” isn’t really ABACAB, nor ACCAABBAAC. It’s actually ABABCABD.
WHEN YOUR MIND GOES CRASH BANG WOOSH is AABCCBACCBA.
Abracadabra is a powerful word, not to be confused with “Debra Kadabra”. It’s also an album by everybody.
“Pioneers Over C” is ABCDEABCDFGABCDEH, a really nasty bugger.
“Space Shanty” is ABCDEFGHIJKCLMB. Yeah, those fellows sure didn’t like repeats.
Humans repeatedly think the darnest things.
