I'll be there with bells on American positive

Thanks for your wedding invitation. I will be there with bells on
The phrase derived from in the late 19th/early 20th centuries and most of the early citations of it suggest a US origin. The first record of it that was found in print is from The Oakland Trbune, June 1904, in a report of a boxing match:
"Jeff will without doubt be in good condition by the last of the month and barring further accidents will be there with bells on".
The phrase is paralleled in the UK by 'with knobs on', which means, 'with additional ornament'.
While "With bells on" is largely reserved as being an enthusiastic response or as indicating additional ornament, both it and 'with (brass) knobs on' are also used as aggressive responses to a challenge. One might hear all of these in conversation. (Source: phrases.org.uk)
