Chronology:Don't Let's Start

Song name	Run time	Releases	Year	Differences from other versions
Don't Let's Start (Demo)	1:14	1985 Demo Tape; Then: The Earlier Years	1984	Synth-filled demo with far fewer lyrics than its album counterpart (No verses, only the choruses and bridge).
Don't Let's Start (Early Mix)	2:39	Dial-A-Song; The Frank O' Toole Show	1986	Early mix of the album version featuring different guitar parts and an alternate vocal take from Linnell, who adds interjections of "uh" and "eh" before the second verse and a "wooo" to close out the song
Don't Let's Start	2:36	They Might Be Giants, A User's Guide to They Might Be Giants: Melody, Fidelity, Quantity	1986	Much more audible synth bass compared to the single mix
Don't Let's Start (Single Mix)	2:35	Don't Let's Start (EP); Don't Let's Start (Album); Miscellaneous T; Then: The Earlier Years, Dial-A-Song: 20 Years Of They Might Be Giants	1987	The main difference between this mix and the album version is in the "I don't want to live in this world anymore" section. This version adds a bass synth that plays underneath Linnell's vocal. Overall, the instrumentation in this mix is a little more spaced out, and the mix contains more reverb.
