I is for: 'I Think We're Alone Now' - Tommy James & The Shondells (1967) / Tiffany (1988)*
*And also Girls Aloud, but their version was uncharacteristically woeful and pointless. For shame, Girls Aloud.
(So check this out for inter-textual pop-geekery: My choice for 'H' (Heaven Is A Place On Earth) was knocked off the Number One spot in 1988 by my choice for 'I' (I Think We're Alone Now).You might - but probably won't - be interested to learn that the song that knocked Tiffany off Number One was another 'I' record, Kylie's 'I Should Be So Lucky', completing a remarkable triple-whammy of 80s Girl Pop chart dominance during this period.)
So, I have A Bit Of A Thing for 80s / early 90s Super Pop; The Bangles, Pat Benatar, Go-Gos and Ex Go-Gos...and yes, even Tiffany. Well...not really Tiffany. But this song at least, and one good song is all that matters. I've dug Tiffany's version on some level ever since I was a kid, but only I only found out that it was a cover-version a couple of years back. I like pretty much both versions equally. They have different things going for them, but they fulfill the same remit in their respective eras, that of being Definitive Bubbblegum Pop.
Tiffany's video for this, if you recall, was filmed in a mall. If you want to know what US teen-culture looked like in 1987, watch this video. It tells you everything you need to know. If you want to know what US teen-culture looked like in 1967...go buy the Doors first album. But also take three minutes to listen to The Shondell's original version of I Think We're Alone Now, because although it couldn't have less to say about the Woodstock Nation, it's certainly a very enjoyable slice of MOR Apple Pie pop-rock, and has the edge on 'Light My Fire' in that it's like about a fith as long, and has a chirrping crickets sound effect on it, and no matter how much acid he gulped, Jim Morrison never thought to put insect sound effects on his records.**
**Tiffany had the good sense to repeat the crickets sound effect at the beginning of her version, a pretty cool nod to the original. Thus ends the nerdiest A-Z post so far.
